Multiple uniqueKey fields
Hello, I just started using Solr and have a question regarding unique keys. Is it somehow possible to specify more than 1 unique key? The problem is, some of my indexed data has one particular unique field, while other data does not have this field at all and uses another field for unique-ness. Any suggestions on how to overcome this? Thanks, David _ Peek-a-boo FREE Tricks & Treats for You! http://www.reallivemoms.com?ocid=TXT_TAGHM&loc=us

Solr java tutorial
Hi everyone, My next question is: is there a beginner's tutorial on how to programmatically query solr? I have seen some users' do things like: SolrServer server = getSolrServer(); SolrQuery solrQuery = new SolrQuery(); solrQuery.setQuery(..); QueryResponse rsp = server.query(solrQuery); But is there some tutorial that outlines the basic classes to use, etc? I know there is a javadoc but it's not helpful if I don't know what to use. Thanks a lot, David _ Help yourself to FREE treats served up daily at the Messenger Café.

Query multiple fields
Hello, I've been trying to figure out how to query multiple fields at a time. For example, I want to do something like: description:test AND type:10. I've tried things like: "?q=description:test&type:10" etc, but I keep getting syntax errors. Can anyone tell me how this can be done? Thanks, David P.S.

RE: Query multiple fields
Hi Nick,
Maybe you can help me with this related problem I am having.
My query is: q=description:(test)&&!(type:10)&&!(type:14).
However, my results are not as expected (55 results instead of the expected 23)
The response header shows:
"responseHeader":{
"status":0,
"QTime":1,
"params":{
"wt":"json",
"!(type:10)":"",
"!(type:14)":"",
"indent":"on",
"q":"description:(test)",
"fl":"*"}},
I am confused about why the "&&!(type:10)&&!(type:14)" is not in the 'q'
parameter.
Any ideas?
Thanks,
David

RE: Query multiple fields
Hi,
According to the Lucene query syntax:
"The symbol && can be used in place of the word AND." So, I shouldn't have to
use 'AND'.
If I do the same query: q=description:(test)&&!(type:10)&&!(type:14) in the
Solr admin interface, I get the correct results.
Re: special characters:
"To escape these character use the \ before the character. For example to
search for (1+1):2 use the query".
I am not searching for "&&" or "!" or "(". So, I shouldn't have to escape
these characters either.
Is my thinking incorrect?
Thanks,
- David

Pagination with Solr
Hello again, I'm trying to accomplish very basic pagination with my Solr search results. What I'm trying is to parse the response for "numFound:" and if this number is greater than the "rows" parameter, I send another search request to Solr with a new "start" parameter. Is there a better way to do this? Specifically, is there another way to obtain the "numFound" rather than parsing the response stream/string?

Tips for searching
Hello, I was wondering if someone could offer some suggestions for a problem I am having. When I perform a query on a field using a single character, I get no results back: for example, if i search on the "description" field for the character 'a', i.e. (description:a), I get no results back. I would like to get all documents where the letter 'a' appears in the description field. I haven't played around with any of the settings in my schema.xml, so I am wondering if someone could point out how I could configure Solr such that it will return me all documents with an 'a' (or any arbitrary character) in the description field. If this could be expanded to match any sub-word (i.e. match "the" in "weather") that would be great as well.

Thanks for the quick response Mike... Ideally it should match more than just a single character, i.e. "the" in "weather" or "pro" in "profile" or "000" in "18000".

If i try a query such as "*", I get an exception which basically says there is a maximum of 1024 clauses for a BooleanQuery. However, if I enter "*:*" it matches all documents and returns them.
