I’ve problem with ferret (acts_as_ferret). search-engine and webserver
are on the same machine. I use acts_as_ferret :field => … to define
which columns are indexed. I recreate the index with
Search.rebuild_index (Search is my model).
To find some results, I use Search.find_with_ferret(“keyword”, {}, {}).
Sometimes, I merge conditions to this query in the last hash. I create
an index over 7’000 records.
For a while, the search is run correctly. Suddently, after perhaps 10
requests, I receive the error message below and the search doesn’t run
anymore.
Has someone a solution for this problem??? Thanks for helping!
