What are the search changes for Engineering Village?

metal OR alloy AND ductile

((metal OR alloy) AND ductile)

(metal OR (alloy AND ductile))

"artificial intelligence" OR AI AND "deep learning" NOT "machine learning"

(("artificial intelligence" OR AI) AND "deep learning") NOT "machine learning"

"artificial intelligence" OR (AI AND ("deep learning" NOT "machine learning"))

Example 1:

(measure NEAR/6 emergency) WN TI

Search results for Example 1 search query must have the terms "measure" and "emergency" located within six terms of each other in any order in the document's title.

• A team task complexity measure for emergency procedures
• Method and system for triggering an emergency measure
• Common organics as samples to measure radioxenon after nuclear emergency

Example 2:

(((lower NEAR/3 limb) OR (lower NEAR/3 extremity)) WN TI)

Example 3:

((time ONEAR/0 travel) WN TI)

is NOT the same search query as

((travel ONEAR/0 time) WN TI))

In the following search query:

((time ONEAR/0 travel) WN TI)

All search results must contain the term time preceding the term travel with no words in between these two words within the TITLE field.

In the following search query:

All search results must contain the term travel preceding the term time with no words in between these two words within the TITLE field.

((travel ONEAR/0 time) WN TI))

For more precise search results, Engineering Village recommends using double quotation marks or curly braces to perform your search query (rather than using the proximity operator with a 0) to ensure correct search results.

For example, if you want your search results to reflect "time travel," then perform the following search:

"time travel" WN TI

If you want your search results to reflect "travel time," then perform the following search:

"travel time" WN TI

Example 4:

((stress NEAR strain) WN CV)

Proximity searches no longer find documents where the matched words are located in separate terms within the CONTROLLED VOCABULARY (‘CV’) field. Previously, the search results for this example matched the adjacent search terms "stress" and "strain" from the ‘CV’ terms field, but the adjacent matches originated from separate controlled vocabulary terms (e.g., "Shear stress" - "Strain energy") within this field. Now the search results will include only individual controlled vocabulary terms that match the words from the proximity search queries. Each of the controlled vocabulary terms for Example 4 contain three words and match the two words in the search query within four words of each other.

• Stress Strain Properties
• stress-strain relations
• Stress-strain curves

Example 5:

((stress NEAR/4 test WN CV)

As described in the Example 4, the search results will include only individual controlled vocabulary terms that match the words in the proximity search query. For Example 5 search query results, some of the controlled vocabulary terms have three words, some have four words, and one of them has five words. All controlled vocabulary search terms contain the search terms "stress" and "test" within four words of each other.

• water avoidance stress test
• stress test procedure
• chronic social defeat stress test
• chronic mild stress test
• stress relaxation test
• Trier Social Stress Test

Example 6:

"Artificial intelligence" NEAR "computational" WN TI

Search results will have the terms "artificial intelligence" located within four words of the term "computational" within the document title.

Document title examples:

• Computational artificial intelligence
• Artificial intelligence and computational design

Example 7:

{computational} NEAR {artificial intelligence}

The search terms for this query are located in component fields of the composite ‘ALL’ field since no field is requested. Thus, the search engine simply searches for the proximity of each term rather than the exact phrase. The results will contain documents in which "computational," "artificial," and "intelligence" are within four words in any of the component fields within the ‘ALL’ field. Therefore, some of the the search terms could be located in the title, while others are located in the abstract, controlled terms, sourcetitle, etc.

• Title: Artificial computational intelligence for wind-thermal power system
• Controlled terms: Artificial intelligence
• Controlled terms: Computational methods

Example 8:

(((limb ONEAR/3 extremity) OR (extremity ONEAR/3 lower)) WN TI)

Search results for Example 8 search query must have the term limb precede the term extremity or the term extremity precede the term lower and be located within three words of either one within the title of the document. The search terms need to be balanced in the search query so that the terms limb and extremity are adjacent to the ONEAR proximity operator and to their corresponding search terms. Additionally, the proximity operator cannot be separated by parentheses from the search terms. It is acceptable for the search terms along with the proximity operator to be enclosed in parentheses as shown in this example.

The third example below demonstrates that the term ‘Extreme’ is a derivative of the word ‘extremity’ and the ‘Autostem’ feature has been enabled for these search queries.

• Neural prosthesis for motor function restoration in upper limb extremity
• Upper extremity and lower back moments during carrying tasks in farm children
• Extreme lower probabilities
• A Musculoskeletal Model of Upper Limb for Disabled Extremity

Smith-Lee, A. J. WN AU

Smith Lee, A.J. (hyphen and whitespace insignificant)

Smith Lee, A J (hyphen and periods insignificant)

Smith-Lee , A. J. (additional whitespace before comma insignificant)

Brown-Gaston, R. L. WN FIRSTAU

Brown Gaston, R.L. (hyphen and whitespace insignificant)

Brown Gaston, R L (hyphen and periods insignificant)

Brown-Gaston , R. L. (additional whitespace before comma insignificant)

University of Illinois at Urbana-Champaign WN AF

University of Illinois at Urbana Champaign WN AF

These two queries yield the same results as the hyphen is insignificant in this case.

{Smith-Lee, A. J.} WN AU

OR

"Smith-Lee, A. J." WN AU

{Smith-Lee, A.J.} WN AU (whitespace insignificant and hyphen is significant)

"Smith-Lee, A J" WN AU (periods insignificant)

{Smith-Lee , A. J.} WN AU (additional whitespace before comma insignificant)

{Lang, Jean Paul} WN AU

{Murray-Smith, R.} WN FIRSTAU

{Murray Smith, R.} WN FIRSTAU is not an equivalent exact search query to the one in the ‘Exact search examples’ column because this query doesn't contain a hyphen in it.

By not including a hyphen in this search query, the results will not find records in which the author's name contains a hyphen.

"Wright-Patterson University" WN AF

{Lange} WN AU

Previous search results for this field:

• Lange, Jens (Lange is a surname)
• de Lange, Willem (Lange is a component of a surname)
• Smith, Lange (Lange is a first name)

Current search results:

Records which contain only the name "Lange" in them are returned in the search results. These records contain the name "Lange" as either a one-word company name or as a name with no other information (no first name and no surname) in them.

{Smith} WN FIRSTAU

Previous search results for this field:

• Smith, Scott (Smith is a surname)
• Murray-Smith, Willem (Smith is a component of a surname)

In Expert search, truncation can be used to represent the beginning year or ending year in year range searches

To find documents published in 2018 or after:

(2018-* WN YR)

• This feature is especially useful when saving a search alert to return results for any end year, not just the current year.
• Alternately, you may select ‘Latest’ from the ‘Published’ dates dropdown menu from the ‘Date’ tab if you do not want to use the YR field in your Expert search query or if you are working from the Document results list after performing a Quick search query.

There is no limit to the total number of wildcards in a search query.

(comput* OR intel* OR artif* OR emerg* OR collab* OR invest* OR meas* WN TI)

There is a limit of three (3) wildcards per search term.

Valid query:

((experim??? OR test??? OR techni???) WN TI).

Syntax error due to exceeding the maximum number of wildcards in a search term:

(([E???-0?(20??)??]) WN STDID)

Truncation search queries require two or more characters for all fields except AUTHOR (AU) and FIRST AUTHOR (FIRSTAU).

Truncation search queries require one or more characters for the AUTHOR (AU) and FIRST AUTHOR (FIRSTAU) fields. The parentheses in these search queries must be properly nested to be valid.

The AUTHOR and FIRST AUTHOR fields require the following rules when using truncation to avoid syntax errors:

• One or more characters
• Proper use of parentheses for correct nesting of the search query

Examples:

((Bailey S*) WN AU)

(Grahn R*) WN AU

(Kumar P?) WN AU

((Smith, R?) WN AU)

((Browning K*) WN FIRSTAU)

Syntax errors will be created for the following search queries in which one or both of the rules listed above were not followed while using truncation:

(Bailey S* WN AU)

(R* WN AU)

(Grahn, R*) WN AU))

Kumar P* WN AU

(Browning K* WN FIRSTAU)

Search terms beginning and ending with truncation operators are not permitted.

Wildcards and truncation are now supported in exact phrase searches.

In the following example, documents that contain derivatives of the root terms ({comput* intel*}) are found within the ABSTRACT field.

In the following example, documents that contain derivatives of the root terms ("emerg*" and "tech*") are found within the within the TITLE field.

The NEAR proximity operator now supports being used with wildcards or truncation.

In the following search query, the terms "meas*" and "emerg*" are expanded to various forms of these terms (e.g., "measure," "measurement," "measures," "measuring," "emergencies," "emerging," "emergent," "emergence,") etc.

• Measures for Expressway Emergency
• Measurements of Emerging Solar Cells

In the following search query, the search phrases "auto* software*" and "mach* learn*" are expanded to various forms of these terms (e.g., "automated," "automatic," "automating," "automotive," "machine," "machine-learning," "learn," "learning," "learning-based,")etc.

• Automatic Software Architecture Recovery:  A Machine Learning Approach
• Machine Learning-based Automated Software
• Machine Learning Algorithms for Automotive Software 

Refer to How do I use the Proximity / NEAR and ONEAR Operators for more information.

The ONEAR proximity operator has been reinstated and now supports being used with wildcards or truncation.

In the following search query, the terms "meas*" and "emerg*" are expanded to various forms of these terms (e.g., "measure," "measurement," "measures," "measuring," "emergencies," "emerging," "emergent," "emergence,") etc.

The title will contain these search terms within three words of each other.
