Index query apostrophe

Hi all,

I need to query my index with a querystring containing an apostrophe.

I would like to retrieve the same results if I query with l'auca or auca querystring.

This is my field definition:

Code:

   /** The title. */
       @Field(name = "title_filter") // here I can use , analyzer=@Analyzer(....) maybe that solves the problem
   private String titulo;

I am searching using the title_filter field.

Thanks in advance,

just use the standard analyzer, both on the @Field and on the input to the Query (we do that automatically if you use the Query DSL)

Hi!

I have been trying to make it work but for the moment it doesn't work. If I search l'auca it works but I would like to search for auca and get the same results. I have checked my index with luke and the field is indexed with apostrophe (l'auca).

This is my field definition:

Code:

       @Field(name = "title", analyzer=@Analyzer(impl=StandardAnalyzer.class))
   private String titulo;

This is my query creation:

Code:

org.apache.lucene.queryParser.QueryParser parser = new QueryParser(Version.LUCENE_31, campos[cont], new StandardAnalyzer(Version.LUCENE_31) );

any help would be very appreciated :)

Thanks in advance,

Hibernator.

One thing I could think about is that you are not using the same Lucene version when you create the standard analyzer. In the query you are using you use Version.LUCENE_31, but depending on the Search version you are actually using it should probably be Version.LUCENE_36.

@Analyzer(impl=StandardAnalyzer.class) will under the hood use the version of the current Lucene version used by Hibernate Search unless you specify explicitly hibernate.search.lucene_version in your configuration.

That said, you can avoid all the hassle if you are using @AnalyzerDef to create a named analyzer which you then can use in your annotations as well as in the query creation via SearchFactory#getAnalyzer(String name). Or you could try the query DSL.
