Re: how to create a custom queryparse to handle new functions
I think you and Shalin are having a vocabulary problem. you used the term function which has a specific meaning in Solr, if you want to write a new function, which works with the existing Function syntax solr provides, and can be nested inside of other functions, then what you want to write is a ValueSourceParser. If you want to write your own Query parser with an entirely new syntax (in which you want things to look like function calls and produce query objects) then you need to implement a QParserPlugin. Some pointers about both can be found here... http://wiki.apache.org/solr/SolrPlugins : You do not need to create a custom query parser for this. You just need to : create a custom function query. Look at one of the existing function queries : in Solr as an example. : : This is where the need originates from - : http://www.lucidimagination.com/search/document/a4bb0dfee53f7493/how_to_scan_dynamic_field_without_specifying_each_field_in_query : : Within the function, the intent is to rewrite incoming parameter into a : different query. Can this be done? AFAIK, not. : : Cheers : Avlesh : : On Sat, Sep 5, 2009 at 3:21 AM, Shalin Shekhar Mangar : shalinman...@gmail.com wrote: : : On Sat, Sep 5, 2009 at 2:15 AM, gdeconto gerald.deco...@topproducer.com : wrote: : : : Can someone point me in the general direction of how to create a custom : queryparser that would allow me to create custom query commands like : this: : : http://localhost:8994/solr/select?q=myfunction(http://localhost:8994/solr/select?q=myfunction%28 : http://localhost:8994/solr/select?q=myfunction%28�Foo�, : 3) : : or point me towards an example? : : note that the actual functionality of myfunction is not defined.

how to create a custom queryparse to handle new functions
Can someone point me in the general direction of how to create a custom queryparser that would allow me to create custom query commands like this: http://localhost:8994/solr/select?q=myfunction(‘Foo’, 3) or point me towards an example? note that the actual functionality of myfunction is not defined. I am just wondering if this sort of extensibility is possible. -- View this message in context: http://www.nabble.com/how-to-create-a-custom-queryparse-to-handle-new-functions-tp25301698p25301698.html Sent from the Solr - User mailing list archive at Nabble.com.
