How can I search within comments in a topic?

You can create an index to search within comments in a topic.

Symptom

I want to search within comments that are encapsulated with <!– -->.

Problem

This index is not defined in the default configuration and must be added manually.

Solution

This index creates a column titled XML Comments that will indicate either no comment or contains comments.

In the TEXTML Administration perspective, perform the following:

Edit the Index Definition file to add the following index:

<index NAME="comments" SYNC="False">
          <stringindex KEEPEXTRACTEDVALUES="True">
              <elements>
              <element XPATH="if (//*[comment()]) then 'contains comments' else 'no comment'" DEPTH="INFINITE"/
             </elements>
         </stringindex>
</index>

In the summaries section, add the following field:
```
<field NAME="comments" TYPE="Index" VALUE="All"/>
```
To add the index to the Advanced Search panel in the Search view, edit the system/conf/advancedSearchIndexes.xml file and add the following:
```
<index attr="false" display="XML Comments" listable="true" name="comments" type="index" views="ALL"/>
```
To display a column named XML Comments in the Search Results view and other views, edit the system/conf/display.xml file and add the following:
```
<key halign="LEFT" label=" XML Comments" name="comments" sortOrder="ASC" sortType="ALPHA" type="Index" visibility="255" width="30"/>
```
Right-click on your Content Store. Click Rebuild All Indexes.
When the indexing is complete, restart your IXIASOFT CCMS Desktop.
Add the new column to your Search Results view.
