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

Check out:
http://svn.apache.org/viewvc/lucene/solr/trunk/client/java/solrj/test/org/ap
ache/solr/client/solrj/SolrQueryTest.java?revision=555343&view=markup
or
http://svn.apache.org/viewvc/lucene/solr/trunk/client/java/solrj/test/org/ap
ache/solr/client/solrj/SolrQueryTest.java?revision=555343&view=markup
as for stability, I've been using solrj for ~6 months now and it's been
great. You should also be able to use the 1.3 pre-release solrj jar files
against a solr 1.2 instance.

Subject: 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

Not really--there have been a few threads on this topic recently.
Perhaps in a couple months?
It may depend on the timing of the lucene release.

It has not been officially released yet. While it is quite stable, the
interfaces are still subject to change until the final release.

Not yet, but there should be!
Currently people learn it from looking at the source and tests. I
started to add something to:
http://wiki.apache.org/solr/Solrj
it (obviously) still needs work.
If you are using eclipse (or similar), after typing "solrQuery." you
should get a drop down of all the available options - i find this
invaluable for learning what is possible.

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:

solrQuery.setQuery(..);
QueryResponse rsp = server.query(solrQuery);
But is there some tutorial that outlines the basic classes to use, etc?

Re: Multiple uniqueKey fields
Posted by Walter Underwood <wu...@netflix.com>.
I had a similar problem with three sources of keys that have collisions
between the values. I prefix a single letter for each source.
movies: M12345
people: P12345
and so on.

key = sometimesUniqueField + "_" + otherTimesUniqueuField;
If one of them is always guaranteed to be unique you should be fine.

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?
