MaxRows and disabling sort
Hi, I want to limit my SOLR results so that it stops further searching once it founds a certain number of records (just like 'limit' in MySQL). I know it has timeAllowed property but is there anything like MaxRows? I am NOT talking about 'rows' attribute which returns a specific no. of rows to client. This seems a very nice way to stop SOLR from traversing through the complete index but I am not sure if there is anything like this. Also I guess default sorting is on Scoring and sorting can only be done once it has the scores of all matches so then limiting it to the max rows becomes useless. So if there a way to disable sorting? e.g. it returns the rows as it finds without any order?

Re: solr speed issues..
I am using three solr cores and all the cores are on the same m/c My configuration is such that i have a machine where code resides and there are 10 other machines which contains the indexed data in cluster.so the code machine picks up a random machine for getting solr data. Also the reason why no of rows are 500 for my application is because i am selecting a text field and based on the 500 results i am calculating word-frequency array,i cant reduce the rows to less than 500 or else the application wont work as expected.. The data comes over the network and is in compressed form,also the data in stored in compressed form. Also the memory allocated for JVM is 1GB which is fair enough. so,without reducing the rows fetch on single solr call i need to speed up the process.So plz suggest the solution in this direction. -- View this message in context: http://lucene.472066.n3.nabble.com/solr-speed-issues-tp2254823p2260692.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: MaxRows and disabling sort
It still returns me (total) 'numFound' that means its scanning all records. So it seems except timeAllowed there is no way to tell SOLR to stop searching for all records? Thanks!

Lucene 2.9.x vs 3.x
Hi, SOLR 1.4.1 uses Lucene 2.9.3 by default (I think so). I have few questions Are there any major performance (or other) improvements in Lucene 3.0.3/Lucene 2.9.4? Does 3.x has major compatibility issues moving from 2.9.x? Will SOLR 1.4.1 build work fine with Lucene 3.0.3?

Implementing Fuzzy Search using OWA operator and Fuzzy Linguistic Quantifier
I am solr-1.3.0 user , where we have integrated Nutch. I want my query types to be like eg. at least "some query", or most of "some query" This is to be done through Fuzzy Search techniques. I know there is fuzzy search in solr using ~(tilde ) sign like e.g."somequery"~0.8 But we want query to be of above types because its convenient to user to ask for what he/she really mean. It happens that using AND, OR , NOT for a user is difficult as user doesnot know where to use AND and where to use OR in the terms. The logical operators become difficult to use in search query. Any one have any idea on how to proceed to implement this?

Re: Implementing Fuzzy Search using OWA operator and Fuzzy Linguistic Quantifier
The query will be like
1. " at least (lucene) "
2. " mostly (solr) "
3. Q(query)="most"(t1,t2,t3,t7) where t1,t2,t3,t7 are terms
4. Q=(t1,0.9) and {(t2,0.5) or (t3,0.7)}
Actually the purpose to expand the query types enterd by user.

Re: spell suggest response
Hi Grijesh, Sounds interesting. Do you have an example of this on some public site that one could see? I'm mainly curious and want to see how it compares to auto-complete on http://search-lucene.com for example.
