Making fields unavailable for return to specific end points.
We have a few internal fields that we would like to restrict from being returned in result sets. I have seen how fl is used in specify fields that you do what returned, I am kind of looking for the opposite. There are just a few fields that don't make sense to return to our clients. Is there any functionality for a blocked-fl? Thank you! -- Andrew NOTICE: This email message is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

RE: Query.toString printing binary in the output...
I have not. Just guessing, but that looks like code that walks a query and
uses the schema to figure out what the types should be.
That looks like the call I should be using. Any idea of how much of
performance impact this has compared to just the Query.toString call (that
admittedly doesn't always work)?
I haven't used the debug option either, but I don't think that is the right
path because we are currently logging all of the queries, and that seems to be
targeted more at a one off operation. (Still helpful to know for those cases
though. Thank you.)

Did you try QueryParsing.toString? As in:
logger.info(db retrieve time= + (System.currentTimeMillis() - start) + ,
query= +
QueryParsing.toString(rb.getQuery(), rb.req.getSchema()) + ,
indexIds= + getIndexIds(rb));

rb.getQuery().toString().replaceAll(\\p{Cntrl}, _) + , indexIds=

When preparing the query we have to encode the collection IDs like this:
Query q = new TermQuery(new Term(SolrTag.COLLECTION_ID.getName(),

So perhaps I am using the wrong term when I used encoded, maybe it should have

(Perhaps we should be using something other than readableToIndexed?)

If you simply attach debug=all to your URL, you should see the query come back
in your response, XML, JSON, whatever. If that also shows bizarre characters,
then that will give you some idea whether it's in Solr or not.
But you haven't given us much info about how/where you call toString. You may
be getting into trouble with character sets (although I'd find that quite odd,
but its a possibility.
What I'm really finding confusing is that you're mentioning Term alongside
query.toString() (at least that's what I think you're saying), which has
nothing at all to do with Terms, it's just the query string passed in. So I'm
really puzzled as to what you're doing to get this kind of output, it almost
looks like you're trying to print out the _results_ of a query, not the query.
So some clarification would be helpful...

RE: Query.toString printing binary in the output...
This is perhaps more clear:
Assuming you have a schema where:
field name=collection_id type=integer indexed=true stored=false
required=true omitTermFreqAndPositions=true/
Then:
void testSamplePrint()throws IOException, SAXException,
ParserConfigurationException{
SolrConfig config = new SolrConfig(solrconfig.xml);
IndexSchema schema = new IndexSchema(config, schema.xml, null);
TermQuery aTerm=new TermQuery(new Term(TestString,123456));
TermQuery bTerm=new TermQuery(new Term(TestString,
schema.getField(collection_id).getType().readableToIndexed(123456)));
System.out.printf(%s\n, aTerm.toString());
System.out.printf(%s\n, bTerm.toString());
assertEquals(aTerm.toString(),bTerm.toString());
}
The test output is:
java.lang.AssertionError:
Expected :TestString:123456
Actual :TestString:`
I believe that this is because the Term does not know that it contains an
encoded integer, and thus cannot parse it. If the TermQuery knew the type, it
could also decode it. But w/o a query to the schema, I don't know how to get
the toString to function correctly.

Best way to convert a field in a query to a fq?
I want to modify incoming queries such that a field is always transformed to a filter query. For example, I want to convert a query field like q= ... part_page=3 ... to a filter query like q= ... fq=partpage(3) . Is the right way to do this in a custom component, or is there someplace else where this should be handled? We have several clients and would like to protect the server from this field being queried on even if they make a mistake.

I want to modify incoming queries such that a field is always transformed to a filter query. For example, I want to convert a query field like q= ... part_page=3 ... to a filter query like q= ... fq=partpage(3) . Is the right way to do this in a custom component, or is there someplace else where this should be handled? We have several clients and would like to protect the server from this field being queried on even if they make a mistake.

Possible to configure the fq caching settings on the server?
Is it possible to configure solr such that the filter query cache settings is
set to fq={!cache=false} by default?

filterQuery (fq=) vs q differences other than scoring.
I know that fq's are used to improve performance by reducing the data set that you score. I have read the documentation that says that non-cached fq's are created in parallel to your query, but would like to know more about how that is done. Does it do a match on all the FQ's, then AND the resulting doc sets and then once that is done score the query based on the resulting subset of documents? -- Andrew Lundgren lundg...@familysearch.org NOTICE: This email message is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

RE: Solr cache size information
For Filter cache size in memory = size in solrconfig.xml * WHAT (the size of an id) ??? (I don't use facet.enum method) As I understand it, size is the number queries that will be cached. My short experience means that the memory consumed will be data dependent. If you have a huge number of documents matched in a FQ, then the size consumed will be very large, if you get a single match then the cached result will take much less memory. I don't know if there is a way you can bound the cache by memory rather than results. I think all of the solr caches behave this way, but I am not sure.

RE: Solr filterCache size settings...
Thank you for your reply. One clarification, is the maxdocs the max docs in the set, or the matched docs from the set? If there are 1000 docs and 19 of them match, is the maxdocs 1000, or 19? -- Andrew -Original Message- From: Erick Erickson [mailto:erickerick...@gmail.com] Sent: Sunday, November 20, 2011 8:10 PM To: solr-user@lucene.apache.org Subject: Re: Solr filterCache size settings... Each fq will create a bitmap that is bounded by (maxdocs / 8) bytes. You can think of the entries in the fiterCache as a map where the key is the filter query you specify and the value is the aforementioned bitmap. The number of entries specified in the config file is the number of entries in that map. So the cache can take up roughly (assuming the size if 512) 512 * maxDocs / 8 bytes.
