Making lucene search case Insensitive
Regular Member Posts: 144 Join Date: 2/21/11 Recent Posts
Hi All,
I am working with lucene index for the first time. I am facing few issues with it. I have few queries.

1. Is lucene search is case Sensitive.
2. How to make it Insensitive in liferay.

I am passing a value for searching in the query. But i am not able to get the proper results because the query which booleanQuery creates is in lowercase.
The values which lucene stores in capital letter. Because of this iam not able to get the results.

Kindly do post your ideas to resolve it.

regards
Sri

HI Shrikanth,

As per my knowledge, please check with below code,

BooleanQuery searchQuery = BooleanQueryFactoryUtil.create();
searchQuery.addTerm("screenName", keywords, true);

In search query while you addTerm give one extraparameter boolean--> true. This may solve your prob.

There used to be lucene.analyzer setting in portal-ext.properties where it was possible to specify lucene analyzer. It seems to have been moved in 6.1.
http://issues.liferay.com/browse/LPS-16895

Try specifying StandardAnalyzer there.

Did you read Brian Chan's comment in the LPS?

search-spring.xml is under the following directory in liferay source.
liferay-portal-src-6.1.0-ce-rc1\portal-impl\src\META-INF
