Re: Indexing Approach

Thank you very much! This helped a lot in our estimates. One last thing though, will a queue based system work for us? Or are there better suitable implementations? -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html

Re: String concatenation in Streaming Expressions

I think there is a bug here in your query, the syntax is : concat(fields=\"fieldA,fieldB\", as=\"fieldABConcat\", delim=\"-\")" Try this: select( search(collection1,q="*:*",fl="conceptid",sort="conceptid asc",fq=storeid:"59c03d21d997b97bf47b3eeb",fq=schematype:"Article",fq=tags:"genetics",

Re: Storing documents with multiple primary keys

I have to ask "why can't you just store the second type with the same field names?" Or do they also have fields A, B and C? It's possible to store these in separate _collections_, configured as you see fit and use "collection aliasing" to search them both with a single query, but that won't solve

Re: Java library for building Streaming Expressions

From my experience this is still limited and lot of things are broken if you still want to do it in a strongly typed manner. The only reliable way is to go right now is via a string-expression building route for the streaming expression. That being said, if your expressions are simple enough

what kind of field is title? text_general or something? Sorting on a tokenized field is usually something you don't want to do. If a field has aardvard and zebra, how would it sort? There's usually something like alphaOnlySort. People often copyField from "title" to "title_sort" and search on

Re: Approach for Merge Database and Files

Seriously consider de-normalizing the data at index time. Your indexing client just accesses both the DB and the file system, selects the relevant data from each then indexes that data as a _single_ document. Then there's no joining necessary at query time. It's a common pattern to do extra work
