Configuring the Ignore Words List for FTS indexing

You can configure the Ignore Words List for FTS indexing only for on-premises deployments.

You can configure the Full Text Search (FTS) engine to ignore frequently used words (such as andthebecause, and so on) or words that you do not want indexed. Adding entries to the Ignore Words List saves space in the FTS index and speeds up text searches. The FTS option comes with a default set of ignored words that you can modify as needed.

You can use the arsftsnostem.stp file to avoid the stemming of words before their usage as ignored words in the AR System server . For example, if the arsftsnostem.stp file contains the word already then only the word already is used as an ignored word. The arsftsnostem.stp file is located in the ARSystemInstallDir\ftsconfiguration directory. Accrue searches that contain words from the Ignore Words List do not find any matching AR System  requests for those words. However, the accrue search retrieves requests for the other search terms. For restrictions on FTS, see Limitations of FTS.

Consider the following important points about FTS and the Ignore Words List:

  • The Ignore Words List is different for each supported language.
  • You must perform FTS indexing if you create an entry in the Thesaurus file before restarting the AR System server.
  • When you initiate full text search on a computer, the FTS searcher uses the ignore words configured on the corresponding indexer server. The FTS searcher does not use the ignore words configured on the computer on which full text search is initiated.

  • When you initiate full text search on a computer, the value of the AR_SERVER_INFO_FT_SUPPORT_EXACT_MATCH_SEARCH configuration on the corresponding indexer server is used to perform full text search. The value of this configuration on the computer on which full text search is initiated has no role to play in full text search.
  • You must reindex the data for the changes to the Ignore Words List to take effect.

For information about adding words to the Ignore Words List, see Configuring FTS by using the Server Information form.

AR System  does not support Full Text Search if you have read-only database. For more information about using read-only database, see Using read-only database.
