How do I search a collection through Lucene?

e.g.



This is what I can do right now.

Now I want to pass a collection of strings in place of one single string. How do I do that?

Hi,

you cannot pass a collection of strings, but you could concatenate the strings and pass it as single string. The matching method will apply the right analyzer for the field you are searching on and analyze your concatenate accordingly.

Does that mean there is no simple way of saying search all the strings in the collection (i want to OR them). The query should return all the results that have atleast one word from the collection present in it.

This is what's going to happen. The analyzer will analyze your string and combine the tokens with a logical OR. This is the same for your example ""what to search" - the search terms would be "what", "to", "search" combined by OR. Well, "to" would probably discarded as a stop word, but that depends on the analyzer.

If this is not what you want have a look at phrase query. An alternative to concatenating the strings is to call onField(fieldName).matching(searchString) in a loop.

Thanks a ton. Tried it and it worked!
