Stopwords are common words such as “I,” “a,” “an,” “the,” and so on, that are ignored during the indexing or querying process. Removing the most common words during the indexing process keeps index sizes smaller, which enhances performance.
You can change the list of stopwords in one of two ways:
Edit the list of words in the default stopwords file, Stopwords_en.xml, available in install_location\OmniQ\config\locale, or
Create a new stopwords file and configure the Text Manager to read from the new file by editing install_location\OmniQ\config\TextModule.default.xml and changing the value of the stopwords.filename parameter to point to the new file.
The format of Stopwords_en.xml is as follows:
<Stopwords xml:lang="en">
<Key>the</Key>
etc
</Stopwords>
Because the words on the stoplist are ignored when you
index documents (in other words, the document is indexed as if the
words on the stoplist did not exist), you must make any changes
to the stoplist before you index. If you have already indexed your
documents and you add new stopwords, the words are not included
in your query, but the disk space consumed by that word’s
associated data is not reclaimed until you index your documents
again.
Removing stopwords after you have already indexed your documents has no effect until you index your documents again.
