Liferay by default provides many portlets to support Open Search Framework such as Message Bords, Blogs, Wikis, Directory and Doc. Library, Users, etc.

These portlets have OpenSearch framework Conf. like
<open-search-class>class-name</open-search-class>

Liferay by default sets Lucene to false for faster performance in portal.properties

you should probably change them in portal-ext.properties

index.read.only=false
index.on.startup=false

You probably need to change it to true and change your indexer class to the class name

Example like:
<indexer-class>com. liferay.test.search.Indexer</indexer-class>

This should help you to start with

Hello Himanshu,
Lucene search is based on indexer search.
Liferay provide us different ways to use lucene search to make fetching result fast.
For our own model we can also create its own indexer if required.

For running liferay indexer model like journalArticle blogs etc.. we can use different Query patter to fetch result in customized way.
We can user query like TermQuery, BolleanQuery etc.
and latter we can get excute those query to search ustil to get Hits.

Hits hits = null;
try {
hits = SearchEngineUtil.search(companyId, yourCustomQuery, startIndex, endIndex);
} catch (SearchException ex) {
LOGGER.error("Error occured during company search", ex);
}

Further you can get document through these hits.

By this way we can achieve as per our required result.

Hi Himanshu,

Has your search worked?

Thanks,
Pranay
