Hi Deigo: Not sure of solr-sense, but complex-lsa is an enhanced lsa implementation with TERM-DOCUMENT Similarity, etc. (not found in lsa). The relevance/ranking is again different and is more accurate as it uses the RankingAlgorithm scoring model. The query performance gain with this version is significant from the last release, a TERM-SIMILARITY query that used to take about 8-9 seconds now takes just 30ms to 80ms. Lot of performance improvements ...
