Exact word search in Solr
Hi,
I am doing exact word search in Solr 1.3 and I am not getting the expected results.
I am giving you the sample XML file along with the mail from where search results are fetched.
The following steps were followed to achieve exact word search result in Solr.
1) Schema.xml is configured for title, url and description
<field name="url" type="string" indexed="true" stored="true" required="true"/>
<field name="title" type="text" indexed="true" stored="true" required="true" />
<field name="description" type="text" indexed="true" stored="true" required="true"/>
Commented below lines
<!--<filter class="solr.EnglishPorterFilterFactory" protected="protwords.txt"/>-->
<!--<filter class="solr.EnglishPorterFilterFactory" protected="protwords.txt"/>-->
2) Started Solr server
3) Indexed sample data with title, url & description
5) Assume I am giving (say channelone) as my input search string for exact word search in Solr admin page.
I am getting the following output.It sould show output pertaining to channelone only.It should not display combination of words with “channelone”.I am not looking for case sensitive search here.
< <doc>
<field name="url">http://c2search1/contactus3.html</field>
<field name="title">c2Search1: Contactus3</field>
<field name="description">channelOne</field>
</doc>
- <doc>
<field name="url">http://c2search1/contactus4.html</field>
<field name="title">c2Search1: Contactus4</field>
<field name="description">Channelone</field>
</doc>
- <doc>
<field name="url">http://c2search1/contactus5.html</field>
<field name="title">c2Search1: Contactus5</field>
<field name="description">channelOne@$</field>
</doc>
- <doc>
<field name="url">http://c2search1/contactus6.html</field>
<field name="title">c2Search1: Contactus6</field>
<field name="description">channelOne12@$</field>
</doc>
- <doc>
<field name="url">http://c2search1/contactus7.html</field>
<field name="title">c2Search1: Contactus7</field>
<field name="description">channelOne12@$ab</field>
</doc>
Expected Result
< <doc>
<field name="url">http://c2search1/contactus3.html</field>
<field name="title">c2Search1: Contactus3</field>
<field name="description">channelOne</field>
</doc>
- <doc>
<field name="url">http://c2search1/contactus4.html</field>
<field name="title">c2Search1: Contactus4</field>
<field name="description">Channelone</field>
</doc>
Please help me with the above scenario to achieve the desired output.

Ahmet's point was to declare the text_ws fieldtype and then use it on the
field you want to have an "exact" match.
FWIW: describing your goal as an "exact word search" is missleading, since
your examples are case-insensitive.

You can simply use the fieldType below to achieve this:
<fieldType name="text_ws" class="solr.TextField" positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
Note that there is no WordDelimiterFilterFactory in this type. But probably yours has it.
Hope this helps.
