Hello Itamar, hello Shad, thanks for the fast response.
I could you provide the callstack, but i think it's useless because it's full of calls to IsFinite(State s, OpenBitSet path, OpenBitSet visited) because it is a recursive function. For the same reason i think that using the CI-Build wouldn't change anything. The IsFinite-function is still working recursively. I've tried to replace the recursion with a stack based approach (using Stack<State>), but i'm not sure if my implementation is correct. How ever, if i use my non-recursive version of IsFinite it crashes with a stackoverflow exception in GetFiniteStrings(State s, HashSet<State> pathstates, HashSet<Int32sRef> strings, Int32sRef path, int limit), which is also a recursive function. But this function is to complex for me to convert it into a non-recursive version without exact knowledge what the function should do. In my opinion is the replacement of the recursion with a non-recursive approach the only solution. Does no one else have this problem? I think to have an index with 4000 documents and a size with 15 MB is not so extraordinary. Or is this only a problem how the suggester works? I'm just try to use lucene to build a fulltext query engine for our internal dms system. The system holds currently 450.000 documents with ca. 50 GB of data. I think the final index will be around 2 GB of size. kind regards Oliver > Shad Storhaug <s...@shadstorhaug.com> hat am 7.
