Dynamically Adding query parameters in my custom Request Handler class

Hi, When I initially fire a query against my Solr instance using SOLRJ I pass only, say q=*:*=(myfield:vaue1). I have written a custom RequestHandler, which is what I call in my SolrJ query. Inside this custom request handler can I add more query params like say the facets etc.. so that

Re: Dynamically Adding query parameters in my custom Request Handler class

Hi, Ahmet, Jack, Thanks for the pointers. My requirement is, I would not be having the facets or sort fields or its order as static. For example suppose for a particular scenario I need to show only 2 facets and sort on only one field. For another scenario I may have to do facet.field for a

Re: Dynamically Adding query parameters in my custom Request Handler class

Woah, Mark…. you’re making a search request within a search component. Instead, let the built-in “query” component do the work for you. I think one fix for you is to make your “components” be “first-components” instead (allowing the other default search components to come into play). You

Re: Dynamically Adding query parameters in my custom Request Handler class

Thanks Eric! Appreciate your valuable suggestions. Now I am getting the concept of a search-component better! So my custom class is just this after removing the SOLRJ part, as I just need to modify the query by adding some parameters dynamically before the query actually is executed by SOLR:-

Re: Dynamically Adding query parameters in my custom Request Handler class

Hi Mark, Try using set method instead of add method : params1.set("fl", "id"); I also suggest to use static String for "fl" as you used CommonParams.Q for "q" Congrats for your first search component! happy searching, Ahmet On Saturday, January 9, 2016 11:32 PM, Mark Robinson

Querying only replica's

Hi, (btw, when is 5.5 due? I see the docs reference it, but not the download page) Anyway, I index and query Solr over HTTP (no SolrJ, etc.) - is it best/good to get the CLUSTERSTATUS via the collection API and explicitly send queries to a replica to ensure I don't send queries to the

Re: Dynamically Adding query parameters in my custom Request Handler class

Hi Mark, Yes this is possible. Better, you can use a custom SearchComponent for this task too. You retrieve solr parameters, wrap it into ModifiableSolrParams. Add extra parameters etc, then pass it to underlying search components. Ahmet On Saturday, January 9, 2016 3:59 PM, Mark Robinson

Re: solrcloud -How to delete a doc at a specific shard

I don't really know unless there's _something_ different about the docs, and you could delete by _query_, something like id=XXX AND (condition unique to the doc you want to remove). I'm more concerned about how there got to be duplicate entries in the first place. There really shouldn't be any

Re: Dynamically Adding query parameters in my custom Request Handler class

Sure, you CAN do this, but why would you want to? I mean, what exactly is the motivation here? If you truly have custom code to execute, fine, but if all you are trying to do is set parameters, a custom request handler is hitting a tack with a sledge hammer. For example, why isn't setting defaults

Re: Running Lucene/SOR on Hadoop

You might consider trying to get the de-duplication done at index time: https://cwiki.apache.org/confluence/display/solr/De-Duplication that way the map reduce job wouldn't even be necessary. When it comes to the map reduce job, you would need to be more specific with *what* you are doing for

Selective Replication from master to slave

bq. There's no good reason to have 5 with a small cluster and by "small" I mean < 100s of nodes. Well, a good reason would be if you want your system to continue to operate if 2 ZK nodes lose communication with the rest of the cluster or go down completely. Just to be clear though, the ZK nodes

Re: Running Lucene/SOR on Hadoop

Hi Steve, I cannot remove deduplication at index time, but rather to find duplicates of the document then inform the duplicate data back to user. Yes, I need to query each document of all 40 million rows. It will be about 10 mapper tasks max. Will try the SolrJ for this purpose. Thanks Steve.
