Re: parsing the raw query string?
Hi If you are planning to use Solr via PHP, you can take a look at the Solr PECL extension. http://www.php.net/manual/en/book.solr.php which you can download from here http://pecl.php.net/package/solr There is a SolrQuery class that allows you to build and manage the name-value pair parameters which you can then pass on to the SolrClient object for onward transmission to the Solr server. It is also serializable so you can cache is in the $_SESSION variable to propagate the parameters from page to page accross requests. The SolrQuery class has buillt-in methods to add, update, remove and manage the Facets, Highlighting, MoreLikeThis, Stats, TermsComponents etc. I hope this helps.

I can't even find what operators (if any) are able to be used in the raw query string in the online docs (maybe there aren't any??).

Re: Grouping
Field collapsing has some aggregation functions like sum() and avg(), but the statistics are computed based on collapse groups instead of all documents with the same field value. A collapse group contains documents that were not relevant enough to end up (collapsed documents) in the search result and one or more documents that are relevant for the current search result, that are being displayed in the search result. This number is controlled by the collapse.threshold parameter, that defaults to one. The statistics are calculated based on the collapsed documents, so it is not exactly the same as a sql group by. You can however get similar results when the collapse.threshold is one and add the field value (e.g. price) of the most relevant document to the aggregated statistic. Off course you will have to this yourself on the client side. Hope this clarifies the field collapse functionality a bit.

Re: Embedded for write, HTTP for read - cache aging

I'm curious, now much faster is it in your situation? Erik
Multiple Solr Instances - Multiple Jetty Instances
This may be a silly question but is there any capacity gain if I run multiple jetty instances each having their own SOLR_HOME where each jetty instance/solr will replicate their index from a separate cluster of masters? I have a couple powerful multi-core servers and am not sure if/how a single JVM takes advantage of multi-cores and feel that I could increase my resource usage and hence search capacity by running multiple jetty instances per server as opposed to adding more machines. Physical redundancy aside, is this acceptable practice? Thanks! Amit
Spellchecking - Is there a way to do this?
Hello everybody 1. Have tons of digitalized text with the logical errors in OCR process 2. Have indexed with Solr and is working OK. 3. Have added spellchecker index-based for words and phrases with the hope to offer suggestions with suspicious possible new query expressions, or related query expressions to the actual one with the intention to find documents that have the original expression but contains OCR errors (the user originally have search for state and democracy and the interface will offer stete and demcraci as an alternate query expression) My first problem appears because I need suggestions inclusive when the expression has returned results. It's seems that only appear suggestions when there are no results. Is there a way to do so? The second question is: For the purposes that I've mentioned, is the best way to use spellchecker or mlt component? Or some other (as a fuzzy query)? Thanks a lot German
