Lucene search and stop word on properties

chapeaurouge — Mon, 11 Jan 2010 09:25:57 GMT

Hello all,I have a custom model, which contains a "business_area" property. One of the value of that property is "IT".If I do a search on "IT", I get no result. Doing search on all other values (ie, HR, EDP, etc…) works fine.Is it that lucene considers it as a stop word?Thank you.fred

Hi,

I found the exactly the same problem 2 month ago.
'IT' is a stop word, that's why your search return nothing

Two solutions:
- write your own engine by specifying custom stop words
- Specify a custom indexation type (without tokenised words) for this metadata in the Model (I choosed this solution)

==> In your custom model (XML file)



<aspect name="foo:bar">
         <title>A custom folder aspect</title>         
          <properties>
            <property name="foo:aProperty">
              <title>aaaaa</title>
              <type>d:text</type>
              <mandatory>false</mandatory>
              [b]<!– index in one word –>
              <index enabled="true">
                 <atomic>true</atomic>
                 <stored>true</stored>
                 <tokenised>false</tokenised>
              </index>[/b]
            </property>

…

If you have data in you repository (in your PRODUCTION environement for instance), I think you need to launch a full re-indexation to take this configuration into account for old data…
