Search using parts of the sentence

Hi,

I need to build a search that compare parts of the sentence used and find entities that has this words.

Example text of entity:
1º - nigeria java shopia ção mormaii da ACQUA Preto Fosco

The search should to find entities that has this words, independently on the sequence in which they are in the sentence.

if I try to search with sentence "nigeria hibernate" for example, with this words couldnt get any result. The word "hibernate" no has matching with the text of entity.
Another hand, i try to search "nigeria shopia", the search should get one result. Because the text of entity has the words "nigeria" and "shopia".

I try to build using the method keyword(), but this mode use every word of the sentence.

Code:

junction.must(builder.keyword().onField(field).matching(value.toString()).createQuery());

or
This mode, the text of entity should be in order of value used.

Code:

junction.must(builder.phrase().onField(field).sentence(value.toString()).createQuery());

Thanks

I found one solution for my problem. Do split of text and create a build using a method keyword() for each term.

Example of code:

Code:

String[] terms = value.toString().split(" ");
for (String term : terms) {
   junction.must(builder.keyword().onField(field).matching(term.toString()).createQuery());
}

Hi,
right your approach seems correct, assuming you really need only results which include all the words listed in the sentence.
It is common to require "most" of the words, but not necessarily all of them, that usually makes the system easier to use; in this case you would use should instead of must when creating the Query. Or you can use a QueryParser and have it parse the original sentence directly.
