CA DataMinder content searches support the following logical operators in search terms.
Boolean Operators
Use these operators to refine your search terms by applying Boolean conditions to keywords.
This operator links two search terms. Both must occur in a document to confirm a match. The order in which the terms appear is not important. AND must be in uppercase.
Example: The following search term only returns documents containing both Unipraxis and complain:
Unipraxis AND complain
This operator applies to a single term. The term must not occur in the document. If it does occur, no match is confirmed. NOT must be in uppercase.
Example: The following search term only returns documents if they contain no mention of UXLogiCard:
NOT UXLogiCard
This operator links two search terms. If either or both occur in a document, a match is confirmed. If neither occurs, no match is confirmed. OR must be in uppercase.
Example: The following search term returns any document containing takeover or acquisition, or both:
takeover OR acquisition
This is an Exclusive OR operator. If either search term (but not both) occur in a document, a match is confirmed. If both or neither occur, no match is confirmed. EOR or XOR must be in uppercase.
Example: The following search term returns any document containing either UXLogiCard or UXProPack, but not both:
UXLogiCard EOR UXProPack
Proximity Operators
These operators enable you to filter to content searches based on the proximity of keywords to each other within a document.
This operator allows you to retrieve documents based on the proximity of two terms within a document. If two keywords appear close together in a document (say, in the same sentence), this increases the likelihood that they are conceptually linked and not just random, unrelated occurrences within the document. The order in which the terms occur is not important.
If the second term is within n words of the first term, a match is confirmed. If either term is absent, or if the number of words separating the two terms is greater than n, no match is confirmed. The order in which the terms occur is not important. NEAR must be in uppercase; n is a number.
Example: The following search term returns any document containing such phrases as Unipraxis are planning an imminent takeover:
Unipraxis NEAR6 takeover
Note: If you do not specify a number, NEAR assumes a five word gap (equivalent to NEAR5).
DNEARn is a directional variant of NEARn. For this operator, the order of the two search terms is important. For a document match to be confirmed, the second term must follow the first term within n words. DNEAR must be in upper casein uppercase.
Example: The following search term looks for documents where UXLogiCard occurs no more than 10 words after the word complain.
complain DNEAR10 UXLogiCard
Note: If you do not specify a number, DNEAR assumes a five word gap (equivalent to DNEAR5).
WNEARn is a weighted variant of NEARn with an OR condition.
WNEAR returns documents that contain either of the two terms. However, a document’s confidence level is raised when the gap between the two terms is the same or less than the gap specified by n. In other words, the closer the terms occur within a document, the more likely the document is to be relevant. WNEAR must be in upper casein uppercase.
Example: The following search term looks for documents that contain UXLogiCard or UXProPack. A higher confidence level is given to documents in which UXLogiCard or UXProPack occur six or fewer words apart. Documents that contain only one term, or where the gap is more than six words, are assigned a lower confidence level, because these documents are less relevant to the search.
UXLogiCard WNEAR6 UXProPack
Note: If you do not specify a number, WNEAR assumes a five word gap (equivalent to WNEAR5).
YNEARn is a weighted variant of NEARn with an AND condition.
WNEAR returns documents that contain both of the terms. However, a document’s confidence level is raised when the gap between the two terms is less than the gap specified by n. YNEAR must be in uppercase.
Example: The following search term looks for documents that contain UXLogiCard and UXProPack. A higher confidence level is given to documents in which UXLogiCard or UXProPack occur less than six words apart. The confidence level increases as the terms get closer together, because these documents are more relevant to the search.
UXLogiCard YNEAR6 UXProPack
Note: If you do not specify a number, YNEAR assumes a five word gap (equivalent to WNEAR5).
XNEARn returns only documents where the two terms are exactly n words apart.
Example: The following search term only returns documents in which UXProPack occurs exactly two words after UXLogiCard. This means that documents containing UXLogiCard and UXProPack are returned in the search results. Conversely, documents containing UXProPack and UXLogiCard or UXProPack, UXLogiCard are not returned.
UXLogiCard XNEAR2 UXProPack
This operator applies to two search terms. The order in which the terms occur is important. For a document match to be confirmed, the second term must follow the first. If the second occurs before the first, no match is confirmed. BEFORE must be in uppercase.
Example: The following search term looks for documents where the word complain occurs before UXLogiCard.
complain BEFORE UXLogiCard
This operator applies to two search terms. The order in which the terms occur is important. For a document match to be confirmed, the first term must follow the second. If the first occurs before the second, no match is confirmed. AFTER must be in uppercase.
Example: The following search term looks for documents where UXLogiCard occurs after complain.
UXLogiCard AFTER complain
This operator applies to two search terms. It returns only documents in which the second term is in the same sentence as the first term.
Example: The following search term only returns documents in which Unipraxis and takeover occur in the same sentence:
Unipraxis SENTENCE takeover
This operator applies to two search terms. It returns only documents in which the second term is in the same paragraph as the first term.
Example: The following search term only returns documents in which Unipraxis and takeover occur in the same paragraph. These terms do not need to be in the same sentence.
Unipraxis PARAGRAPH takeover
