Re: [Exist-open] Lucene search issue with existed 2.1

[Joe W. <jo...@gm...>]

Hi Alem,

The words "to" and "the" are included in Lucene's default list of
stopwords. They're dropped when indexing documents and ignored when
querying them. To ensure these words are indexed, you have to either
customize the list of stopwords or explicitly eliminate all stopwords,
adding the following <param> element to the <analyzer> element in your
.xconf file:

<analyzer class="org.apache.lucene.analysis.standard.StandardAnalyzer">
>     <!-- Specify stop words - or remove them entirely -->
>     <param name="stopwords" type=
> "org.apache.lucene.analysis.util.CharArraySet">
>         <!--<value>the</value>-->
>     </param>
> </analyzer>


For the list of words treated as stopwords by default in Lucene, see
https://markmail.org/message/wxmtjzbskgrj2cug. Place any stopwords you want
to keep in <value> elements. By omitting any <value> elements (as shown
above), the you've removed all stopwords. For the current eXist docs on
configuring Lucene's stopword facility, see
https://exist-db.org/exist/apps/doc/lucene#conf.
