Re: help implementing a couple of business rules
For your first question, wouldn't it be possible to achieve that with some simple boolean logic? I mean, if you have a requirement to match any of the other fields AND description2, but not if it ONLY matches description 2: say matching x against field A, B, and description 2: ((A:x OR B:x) AND description2:x) would only give you results from description2 IF there is also a match in either one of the other two fields. If I misunderstood your requirements, you should also note that solr supports pure negative field matching aswell, meaning that you CAN exclude results from a specific field entirely. From the wiki: Pure negative queries (all clauses prohibited) are allowed. -inStock:falsefinds all field values where inStock is not false Hope that helps, Aleks On Mon, Jan 11, 2010 at 7:29 PM, Joe Calderon calderon@gmail.comwrote: thx, but im not sure that covers all edge cases, to clarify 1. matching description2 is okay if other fields are matched too, but results matching only to description2 should be omitted 2. its okay to not match against the people field, but matches against the people field should only be phrase matches sorry if i was unclear --joe On Mon, Jan 11, 2010 at 10:13 AM, Erik Hatcher erik.hatc...@gmail.com wrote: On Jan 11, 2010, at 12:56 PM, Joe Calderon wrote: 1. given a set of fields how to return matches that match across them but not just one specific one, ex im using a dismax parser currently but i want to exclude any results that only match against a field called 'description2' One way could be to add an fq parameter to the request: fq=-description2:(query) 2. given a set of fields how to return matches that match across them but on one specific field match as a phrase only, ex im using a dismax parser currently but i want matches against a field called 'people' to only match as a phrase Doesn't setting pf=people accomplish this?

help implementing a couple of business rules
hello *, im looking for help on writing queries to implement a few business rules. 1. given a set of fields how to return matches that match across them but not just one specific one, ex im using a dismax parser currently but i want to exclude any results that only match against a field called 'description2' 2. given a set of fields how to return matches that match across them but on one specific field match as a phrase only, ex im using a dismax parser currently but i want matches against a field called 'people' to only match as a phrase thx much, --joe
