Re: Replication Backup

Hi Eva, You just need a script that: * calls master with http://replication?command=backup * copies the backup off of master and stores it somewhere * removes that backup from the master if you don't have enough disk for it there Otis -- SOLR Performance Monitoring - http://sematext.com/spm/i

Hi, Does StandardTokenizerFactory remove your numbers? Go to the Analysis page in Solr Admin, enter your query with numbers, and see what happens. Otis -- SOLR Performance Monitoring - http://sematext.com/spm/index.html Search Analytics - http://sematext.com/search-analytics/index.html On Thu

Re: User context based search in apache solr

Right, he has talked about this in various ways. But the key is take the user-item matrix in full and generate a new data model for recommendation. These approaches shove that datamodel into the search index. It is a batch process. LucidWorks does this for search clicks. - Original Message

Re: configuring solr xml as a datasource

You don't need the transformers. I think the paths should be what is in the XML file. forEach="/add" And the paths need to use the syntax for name="fname" and name="number". I think this is it, but you should make sure. xpath="/add/doc/field[@name='fname']" xpath="/add/doc/field[@name='number

Re: Performance improvement for solr faceting on large index

Hi Pravin, Those unigrams... how are you using them? What are the queries like? I wonder if it's the (probably) massive number of terms in your index that's the problem. When queries are in flight and your CPU is 100% busy, do a few thread dumps (kill -3 PID) and look where the threads are. Tha

Re: User context based search in apache solr

On the other hand, people have successfully built recommendation engines on top of Lucene or Solr before, and I think Ted Dunning just mentioned this over on the Mahout ML a few weeks ago. have a look at http://search-lucene.com/m/dbxtb1ykRkM though I think I recall a separate recent email wher

Re: User context based search in apache solr

sagarzond- you are trying to embed a recommendation system into search. Recommendations are inherently a matrix problem, where Solr and other search engines are one-dimensional databases. What you have is a sparse user-product matrix. This book has a good explanation of recommender systems: Mah

Hi Felipe, omitTermFrequencyAndPositions may help, but you may also want to implement a custom similarity class that neutralizes idf. See http://search-lucene.com/?q=custom+similarity Otis -- SOLR Performance Monitoring - http://sematext.com/spm/index.html Search Analytics - http://sematext.com/s

Re: Solr Admin Page authentication

Hi, I added authentication in Jetty and it works fine. However, it's strange that url pattern like "/admin/cores*" is not working, but "/admin/*" works correct. Regards. On 17 November 2012 01:10, Marcin Rzewucki wrote: > Hi, > > Yes, I'm trying to add authentication to Jetty (for solr4), acco

Re: Indexing only on change

Not sure if there is an automated way, but you could do it by computing a hash of various/all fields at index time and later use that to compare before updating. And you can hide this in a UpdateRequestProcessor. Could be a generally useful feature, so consider contributing. Otis -- SOLR Performa

Re: Indexing only on change

I would create a hash of the document content and store that in SOLR along with any document info you wish to store. When a document is presented for indexing, hash that and compare to the hash of the stored document, index if they are different and skip if they are not. François On Nov 24,

Configuring multiple spell checkers

Hi all, I'm trying to configure our Solr 3.4 deployment to have multiple spellcheckers based on 2 different fields, one in English and one in Spanish. In solrconfig.xml, the SpellCheckComponent requires a queryAnalyzerFieldType and each of these fields is based on a different field type for lang

Hello. You can query by *:* with start=0, rows=1, fl=contentid and sorting by contentid. Get the bigger/smaller value for that field is from the first (and only) document returned. Regards, - Luis Cappa. El 24/11/2012 14:45, "Jack Krupansky" escribió: > The "stats" component will give you the

Re: Finding max value from a fieldvalue using solr query

The "stats" component will give you the minimum and maximum values for fields, among other statistics (e.g., number of documents where a field is missing). Just add &stats=true&stats.field=contentid to your query. The counts will be in the "stats" section of the query response. -- Jack Krupa
