Overview of Special Operators

The documents in this section describe the special operators of the Search Cartridge. Where appropriate, each description includes an example of simple syntax and explicit syntax. Operators are listed alphabetically. The relational operators are listed at the end of this section.

Please note that in environments with a locale other than English, the operators must always be preceded by a Pound sign (or hash mark) and enclosed in angle brackets (example: <#AND>).

Furthermore, if and, or, any, all or not or their equivalents in another language are used as search words, then these words must be enclosed in quotation marks. Otherwise they will be interpreted as operator or modifier names.

  • COMPLEMENT

    Calculates scores for documents matching a query by taking the complement (subtracting from 1) the scores for the query’s search elements.

  • CONTAINS

    Selects documents by matching a phrase with values stored in a document field.

  • ENDS

    Selects documents by matching the character string you specify with the ending characters of the values stored in a specific document field.

  • = (equal)

    The operator selects documents whose fields contain exactly the same values as the search string.

  • FREETEXT

    This operator interprets text using the free text query parser.

  • > (greater than)

    The operator returns documents whose fields contain values that are greater than the search string.

  • >= (greater than or equal)

    The operator returns documents whose fields contain values that are greater than or equal to the search string.

  • < (less than)

    The operator returns documents whose fields contain values that are less than the search string.

  • <= (less than or equal)

    The operator returns documents whose fields contain values that are less than or equal to the search string.

  • LIKE

    The LIKE operator searches for documents that are similar to a sample document or text passages you provide.

  • MATCHES

    This operator compares a character string with values stored in a specific document field.

  • != (not equal)

    The operator finds documents whose document fields do not contain the same values as the search string.

  • PRODUCT

    This operator calculates a total score by multiplying individual scores.

  • STARTS

    The operator finds documents in which a field starts with the search string.

  • SUBSTRING

    Finds documents in which a particular field contains the search string.

  • SUM

    Calculates the score of a found document by adding the scores for the query’s search elements.

  • YESNO

    Forces the score of an element to 100, if the element’s score is nonzero.
