Calculate a sum.
hello. My problem is, that i need to calculate a sum of amounts. this amount is in my index (stored=true). my php script get all values with paging. but if a request takes too long, jetty is killing this process and i get a broken pipe. Which is the best/fastest way to get the values of many fields from index? exists an ResponseHandler for exports? Or which is the fastest? -- View this message in context: http://lucene.472066.n3.nabble.com/Calculate-a-sum-tp4033091.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: Calculate a sum.
Hello! Fetching all the documents, especially for a query that returns many documents can be a pain. However there is a StatsComponent (http://wiki.apache.org/solr/StatsComponent) in Solr, however your field would have to be numeric and indexed. -- Regards, Rafał Kuć Sematext :: http://sematext.com/ :: Solr - Lucene - Nutch - ElasticSearch hello.

Re: Calculate a sum.
Hey, thx for your reply. i forgot to say. StatsComponent doesnt work with our application. too slow and buggy. but i test with this component with version 1.4 ... maybe some bugfixes in 4.0 ? this is the reason for calculating the sum on client side and some pages. but sometimes its too much for server. -- View this message in context: http://lucene.472066.n3.nabble.com/Calculate-a-sum-tp4033091p4033097.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: Calculate a sum.
Stored fields are famous for its' slowness as well as they requires two io operation per doc. You can spend some heap for uninverting the index and utilize wiki.apache.org/solr/StatsComponent Let us know whether it works for you. 14.01.2013 13:14 пользователь stockii stock.jo...@googlemail.com написал: hello.

Re: Calculate a sum.
i've had perfectly fine performance with StatsComponent, but have only tested with 50,000 documents. for example i have field syllables and numeric field syllables_count. then i sum the syllable count for any search query. how many documents are you working with?
