DB2 Net Search Extender Administration and User's Guide


Stopwords

Stopwords are words with a high frequency and no relevant content for the text retrieval process. Usually, all function words (in a linguistic sense) are considered stopwords, for example "and", "or", and "in".

Net Search Extender provides stopword processing for a list of languages, where the stopwords are not indexed and therefore, cannot be searched on. However, the result of stopword processing is a smaller and faster text index.

Note that stopwords that are not indexed are processed the same way as normal words during search. However, if a stopword has been indexed, the stopword is ignored during the search process.
