Re: Newbie Question on Custom Query Generation

dismax won't quite give you the same query result. What you can do pretty easily, though, is create a QParser and QParserPlugin pair, register it solrconfig.xml and then use &defType=. Pretty straightforward. Have a look at Solr's various QParserPlugin implementations for details.

Aggregated facet value counts?

Hi, I was wondering if anyone had come across this use case, and if this type of faceting is possible: The requirement is to build a query such that an aggregated facet count of common (and'ed) field values form the basis of each returned facet count. For example: Let's say I have a

Re: Aggregated facet value counts?

When faced with this type of situation where the data is entirely available at index-time, simply create an aggregated field that glues the two pieces together, and facet on that. Erik On Jan 29, 2010, at 6:16 AM, Peter S wrote: Hi, I was wondering if anyone had come across thi

RE: Aggregated facet value counts?

Hi Erik, Thanks for your reply. That's an interesting idea doing it at index-time, and a good idea for known field combinations. The only thing is How to handle arbitrary field combinations? - i.e. to allow the caller to specify any combination of fields at query-time? So, yes, th

Re: Aggregated facet value counts?

Creating values for every possible combination is what you're asking Solr to do at query-time, and as far as I know there isn't really a way to accomplish that like you're asking. Is the need really to be arbitrary here? Erik On Jan 29, 2010, at 7:25 AM, Peter S wrote: Hi Erik

RE: Aggregated facet value counts?

Well, it wouldn't be 'every' combination - more of 'any' combination at query-time. The 'arbitrary' part of the requirement is because it's not practical to predict every combination a user might ask for, although generally users would tend to search for similar/the same query combinations (b

Is optimizing always necessary?

If one only have additions do I then need to optimize the index at all ? I thought that only update/deletes created "holes" in the index. Or should the index be sorted on disk at all times, is that the reason ? Cheers //Marcus -- Marcus Herou CTO and co-founder Tailsweep AB +46702561312 marcus

Re: Aggregated facet value counts?

Sounds like what you're asking for is tree faceting. A basic implementation is available in SOLR-792, but one that could also take facet.queries, numeric or date range buckets, to tree on would be a nice improvement. Still, the underlying implementation will simply enumerate all the poss

Re: Is optimizing always necessary?

In addition to destory the "holes" in the index, optimization is also used to merge multiple small indexes into a bigger one. Although I have not got specific performace data, I can imagine that this will lead to performace benifits. Supposing you have thousands of small indexes, open-close these

I think you can combine serveral solr supplied standard function query to achieve this. similar to: &bf=map(map(div(ms(NOW, expiration),8640),-1,0,0), 1,1,1) Furthermore, you would implement your own function and register it in solrconfig.xml using valueSourceParser tag. 2010/1/29 An
