    Lucene Search Engine results Hebrew

    Hi, I have implemented Lucene Search Engine results in my website, and it works flawlessly, except one distinct issue: When I try to search a Hebrew term that has double quotation marks in it, I get no results. For example: דפ"ר

    this word should return results, but it doesn't.

    Note: wild card works: דפ*

    Any thoughts?

    thanks, Rotem

    You can try to use escape function - please see Lucene documentation https://lucene.apache.org/core/294/queryparsersyntax.html

    Rotem,

    Are you using hebrew analyser? See https://our.umbraco.com/packages/developer-tools/hebrew-search/ this may get round the problem. Ideally when doing multilingual you should use the language specific analyser if available.

    Regards

    Ismail

    just note that HebMorph is not free for commercial use

    from HebMorph website:

    If you are developing a commercial application, please contact us to discuss a commercial license. This helps us support development of future versions that make Hebrew search even better. Paid licenses are bundled with a proprietary dictionary, which replaces the AGPL3'd hspell used by the open-source version, as well as integration support.

    Hi,

    Thank you for the answers. I tried https://our.umbraco.com/packages/developer-tools/hebrew-search/

    and it does not solve the issue :(

    also, when I debug the search I can clearly see that the word is already escaped (דפ\"ר) Meaning: I can see the slash being added to the string, but still, no value is being returned.

    any other thoughts? :)

    thanks

    Thanks, I marked your answer as solution, but unfortunately, Itamar did not replay, so I guess i'll have to face this one myself.

    :)
