It also supports the use of Boolean operators and custom noise word lists as well as the basic searching features available in keyword searches. In dtSearch Web, these three strings are HTML form variables.Relativity's dtSearch engine provides advanced search functionality such as proximity, stemming, and fuzzy searches across any field type. In the developer API, the Request, FileConditions, and BooleanConditions are properties of the SearchJob or DSearchJob (C++).

can be used in any of the three search strings. Search features such as fuzzy searching, stemming, wildcards, etc. If any of these items is blank, it is ignored. BooleanConditions are useful when your application needs to combine a user-entered search request, which may be in the 'all words' or 'any words' syntax, with a boolean combination of field searches.Ī document is retrieved in a search only if it matches the Request, FileConditions, and BooleanConditions. File conditions can also be used to optimize searches for terms or field values, because matches on file conditions do not generate 'hits' in the search results, which enables dtSearch to ignore word location information.īooleanConditions are additional search criteria that are expressed in the boolean query syntax. File conditions use the xfilter syntax described in the 'File Conditions' help topic. Depending on the value of the search flags, it can use the boolean query syntax, or the 'all words' or 'any words' query syntax.įile conditions are usually restrictions based on the file modification date, name, or size. The Request string usually comes from user input. The maximum total size of a search request in bytes is dtsMaxSearchRequestLen, which is defined in dtsearch.h. To accommodate these types of searching, dtSearch can combine three separate string values to form the complete search request. A search request may include any combination of: (1) a full text search request, (2) restrictions based on the filename, modification date, or size, and (3) additional boolean restrictions, such as criteria based on the contents of fields in user documents.
