Configuring the Ignore Words List
You can configure the Full Text Search (FTS) engine to ignore frequently used words (such as and, the, because, 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 must reindex the data for the changes to the Ignore Words List to take effect.
Accrue searches that contain words from the Ignore Words List do not find any matching Remedy 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.
You can use the arsftsnostem.stp file to avoid the stemming of words before their usage as ignored words in the Remedy AR System server.
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.
Note 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 perform full text search on a computer, the FTS searcher uses the stop words configured on the corresponding indexer server. The FTS searcher does not use the stop words configured on the computer on which full text search is performed.
For information about adding words to the Ignore Words List, see FTS tab configuration options.
Remedy AR System does not support Full Text Search if you have read-only database. For more information on using read-only database, see Using read-only database.
