localize AND operator

Hi,

Is there a way (a predefined way) to localize operators of a full text query ?

For example replace "AND" operator by its french counterpart "ET" or german "UND" so that "hibernate ET search" query is interpreted as "hibernate AND search".

Best regards,
Eric

Hi,
the "predefined" answer is that QueryParser is just an example, for best flexibility you should implement your own or extend it.
Personally I would just use a regex to do some replacements in the string.

There are lots of questions like this, do you think we should embed some helper in Search?

You are right, it is not complicated to do string replacement with a regular expression before the query is processed by search engine.

Any way, it could be nice to have a set of translations available for search keywords. The search keyword language could be paramerized along with other hibernate search config parameters.

I asked this, since it is one of our customer requirement.

Best regards,
Eric

that's a lot of time for an answer :-)

Do you have a proposal about how this should work?
Would you be willing to provide some languages as a starter/concept idea to implement it?

For example in hibernateProperties :

<prop key="hibernate.search.keywords.lang">fr</prop>

For french language.

And then a LocalizedQueryParser which would extend QueryParser and performs replacement of keywords in an overriden parse() method. The AND and OR operators would be overriden as well in the localized query parser depending on the hibernate.search.keywords.lang property value.
