Re: Single Core or Multiple Core?
On Fri, Sep 4, 2009 at 4:35 AM, Jonathan Ariel ionat...@gmail.com wrote: It seems like it is really hard to decide when the Multiple Core solution is more appropriate.As I could understand from this list and wiki the Multiple Core feature was designed to address the need of handling different sets of data within the same solr instance, where the sets of data don't need to be joined. Correct. It is also useful when you don't want to setup multiple boxes or tomcats for each Solr. In my case the documents are of a specific site and country. So document A can be of Site 1 / Country 1, B of Site 2 / Country 1, C of Site 1 / Country 2, and so on. For the use cases of my application I will never query across countries or sites. I will always have to provide to the query the country id and the site id. Would you suggest to split my data into cores? I have few sites (around 20) and more countries (around 90). Should I split my data into sites (around 20 cores) and within a core filter by site? Should I split by Site and Country (around 1800 cores)? What should I consider when splitting my data into multiple cores? The first question is why do you want to split at all? Is the schema or solrconfig different? Are the different sites or countries updated at different times? Is the combined index very big that the response times jump wildly when all the caches are thrown out if documents related to one site or country are updated? Does warmup or optimize or replication take too much time with one big index? Each core will have its own configuration files (maintenance) and you need to setup replication separately for each core (which is a pain with the script based replication). Also note that by keeping all cores in one tomcat (one JVM), a stop-the-world GC will stop all cores which is not the case when using separate JVMs for each index/core. -- Regards, Shalin Shekhar Mangar.

Re: Facet search field returning results on split words
Your field needs to be untokenized for expected results. Faceting on the text field that you use to search will give you facets like these. You can index the same data in some other string field and facet on that field. PS: You can use copyField to copy data during index time from one field to other.

Re: Schema for group/child entity setup
can't you store the locations as part of the parent listing while storing. This way there would be only one document per parent listing. And all the locations related information can be multi valued attributes per property or any other way depending on the attributes. 2009/9/3 R. Tan tanrihae...@gmail.com Hi Solrers, I would like to get your opinion on how to best approach a search requirement that I have. The scenario is I have a set of business listings that may be group into one parent business (such as 7-eleven having several locations). On the results page, I only want 7-eleven to show up once but also show how many locations matched the query (facet filtered by state, for example) and maybe a preview of the some of the locations. Searching for the business name is straightforward but the locations within the a result is quite tricky. I can do the opposite, searching for the locations and faceting on business names, but it will still basically be the same thing and repeat results with the same business name. Any advice? Thanks, R
Re: how to scan dynamic field without specifying each field in query
what all other searches you would like to perform on these fields?
From the proposed function definition I believe that when foo*:3 is to be
searched all foo* would be searched and none are to be excluded. Assuming
that this is the only search that are to be performed on these fields, we
might declare the dynamic field foo* and rather than constructing fields
actual name with property key we can construct it with the to be searched
value and store key as the value.
So assume we want to search fooA:X fooB:X fooC:X I would rather store
fooX as the multivalued field and store all A, B, C as its values.
The search query can be FooX:*, that is if field fooX exists, get all the
values for the same.
But again as I asked first, it would depend on what kind of other queries
you want to perform.
regards,
aakash
2009/9/4 gdeconto gerald.deco...@topproducer.com
I am thinking that my example was too simple/generic :-U. It is possible
for
more several dynamic fields to exist and other functionality to be
required.
i.e. what about if my example had read:
http://localhost:8994/solr/select?q=((Foo1:3http://localhost:8994/solr/select?q=%28%28Foo1:3OR
Foo2:3 OR Foo3:3 OR …
Foo999:3) AND (Bar1:1 OR Bar2:1 OR Bar3:1...Bar999:1) AND (Etc1:7 OR Etc2:7
OR Etc3:7...Etc:999:7)
obviously a nasty query (and care would be needed for MAX_BOOLEAN_CLAUSES).
that said, are there other mechanisms to better handle that type of query,
i.e.:
http://localhost:8994/solr/select?q=(myfunction(http://localhost:8994/solr/select?q=%28myfunction%28‘Foo’,
3) AND
myfunction('Bar', 1) AND (myfunction('Etc', 7))

Re: how to scan dynamic field without specifying each field in query
I dont have that answer as I was asking a general question, not one for a specific situation I am encountering). what I am essentially asking for is: is there a short, simple and generic method/technique to deal with large numbers of dynamic fields (rather than having to specify each and every test on each and every dynamic field) in a query what originally prompted this question is I was looking at FunctionQueries (http://wiki.apache.org/solr/FunctionQuery) and started to wonder if there was some way to create my own functions to handle dynamic fields.

Re: how to scan dynamic field without specifying each field in query
I dont have that answer as I was asking a general question, not one for a specific situation I am encountering). I can understand :) what I am essentially asking for is: is there a short, simple and generic method/technique to deal with large numbers of dynamic fields (rather than having to specify each and every test on each and every dynamic field) in a query Not as of now. There are a lot of open issues in Solr aiming to handle dynamic fields in an intuitive way. SolrJ has already been made capable of binding dynamic field content into Java beans ( https://issues.apache.org/jira/browse/SOLR-1129). Faceting on myField_* ( https://issues.apache.org/jira/browse/SOLR-1387) and adding SolrDocuments with MapString, String myField_* ( https://issues.apache.org/jira/browse/SOLR-1357) are just some of the enhancements on the way. what originally prompted this question is I was looking at FunctionQueries ( http://wiki.apache.org/solr/FunctionQuery) and started to wonder if there was some way to create my own functions to handle dynamic fields. I don't think you need function queries here. Function queries are supposed to return score for a document based on their ValueSource. What you probably need is a custom QueryParser.

capturing field length into a stored document field
For various statistics I collect from an index it's important for me to know the length (measured in tokens) of a document field. I can get that information to some degree from the norms for the field but a) the resolution isn't that great, and b) more importantly, if boosts are used it's almost impossible to get lengths from this. Here's two ideas I was thinking about that maybe some can comment on. 1) Use copyto to copy the field in question, fieldA to an addition field, fieldALength, which has an extra filter that just counts the tokens and only outputs a token representing the length of the field. This has the disadvantage of retokenizing basically the whole document (because the field in question is basically the body). Plus I would think littering the term space with these tokens might be bad for performance, I'm not sure. 2) Add a filter to the field in question which again counts the tokens. This filter allows the regular tokens to be indexed as usual but somehow manages to get the token-count into a stored field of the document. This has the advantage of not having to retokenize the field and instead of littering the token space, the count becomes docdata for each doc. Can this be done? Maybe using threadLocal to temporarily store the count? Thanks. -- View this message in context: http://www.nabble.com/capturing-field-length-into-a-stored-document-field-tp25297690p25297690.html Sent from the Solr - User mailing list archive at Nabble.com.
