问题 The Solr documentation for creating your own token and character filters says the following. http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#Specifying_an_Analyzer_in_the_schema If you want to use custom CharFilters, Tokenizers or TokenFilters, you'll need to write a very simple factory that subclasses BaseTokenizerFactory or BaseTokenFilterFactory, something like this... public class MyCustomFilterFactory extends BaseTokenFilterFactory { public TokenStream create(TokenStream

问题 Let me take an example to explain the scenario. Suppose i have data indexed to Solr as : { "id" : "872919092", "filename" : "science_book", "path" : "/local/abc/" } Now i want to modify the data already indexed to Solr with id : 872919092 . I need to change the filename : science_book with filename : history_book and add new attribute topic : mughal to the same indexed data keeping path unchanged. I do not want to pass the path again as there is no change in that and already indexed to Solr.

问题 How can use Solr from within Scala/ Play? Specifically how do I add/ update documents? 回答1: Update: see my newer answer refer https://stackoverflow.com/a/17315047/604511 Here is code I wrote which uses Play's JSON library and Dispatch HTTP client. Its not perfect, but it should help you get started. package controllers import play.api._ import play.api.mvc._ import play.api.libs.json.Json import play.api.libs.json.Json.toJson import dispatch._ object Application extends Controller { def index

问题 I need a way to collapse duplicate (defined in terms of a string field with an id) results in solr. I know that such a feature is comming in the next version (1.5), but I can't wait for that. What would be the best way to remove duplicates using the current stable version 1.4? Given that finding duplicates in my case is really easy (comparison of a string field), should it be a Filter, should I overwrite the existing SearchComponent or write a new Component, or use some external libraries

问题 I'd like to flatten a nested json object, e.g. {"a":{"b":1}} to {"a.b":1} in order to digest it in solr. I have 11 TB of json files which are both nested and contains dots in field names, meaning not elasticsearch (dots) nor solr (nested without the _childDocument_ notation) can digest it as is. The other solutions would be to replace dots in the field names with underscores and push it to elasticsearch, but I have far better experience with solr therefore I prefer the flatten solution

问题 I have difficulties with the "/terms" request handler using Solr 4.2.0. Using the web browser the following url returns the list of terms of the fieldName INDUSTRY http://localhost:8983/solr/collection1/terms?terms.fl=INDUSTRY&terms.prefix=P&terms=true On the other hand, the following query returns no terms: http://localhost:8983/solr/collection1/select?qt=terms&terms.fl=INDUSTRY&terms.prefix=P&terms=true My question is how can I use the "/terms" requestHandler via the "/select"
