The following table provides some issues and solutions for troubleshooting search.

IssueSolution/Information
I get the following error message when running a search:

Invalid search summary configuration. Please contact system administrator.

An invalid XPath was entered for a customized search results display. See Changing the Search Results Abstract

This string, search.summary.invalid, can be localized. See Modifying Language Items

After running a search where I know there are topics that should appear in the results; however, no results are returned.Check the XPath for customized search results display. The XPath may be valid, but is not producing any results. See Changing the Search Results Abstract
I am searching for content that I know is in the publication but the keywords are not found.The search program searches only documents (topics) and not the table of contents (map).

Entities cannot be searched.

When I try to do a multi-language search, I see "Undefined" in the Language drop-down list in the Advanced Search screen.The languages are not fully configured. SeeAdding or Merging a Language
After I reindex, I see this message in the xist.log:

Lucene index configuration error

This occurs if there is an extra slash / in the XPATH field when you set up search categories (for example, //p/ instead of //p).

Other symptoms of an incorrect XPath include re-indexing running very fast and searching after re-indexing always returning zero (0) results.

For details, see Adding Search Categories

I have filtering turned on, but some documents are appearing in search results that I do not expect to see.Check whether the topic has <indexterm>.

If the search phrase is found in the <indexterm>, it is returned in the results.

If you want to keep the <indexterm>, but make sure that it is filtered out of the search, set an attribute on the element. For example:

<indexterm product="A450">A450</indexterm>
