Hi: I have been trying to use (and successfully did) the Significant terms aggregations in release 1.1.0. The blog posts about this feature http://www.elasticsearch.org/blog/significant-terms-aggregation/ was extremely helpful. Since this feature is in experimental stage and the authors had requested feedback and me not knowing about how to provide feedback regarding specific features, I am restarting to posting on this group.
I had posted on a different thread regarding accessing the TFIDF scores for terms so that I could investigate ways in which I could enhance my queries. This lead me to look at the experimental Significant Terms Aggregation. It does what it says quite well. and I am glad this functionality exists. However, I would like to see some possibilities of enhancements: What I noticed in my aggregation results is a lot of Stopwords (a, an, the, at, and, etc.) being included as significant terms. perhaps having the possibility of including Stopword lists so that these stop words are not included in the signifiant term calculations. (The significance is calculated based on how many times a term appears in the query result vs how many times it appears in whole index. ) For common stop words this calculation i going to make them very significant. Another possible enhancement would be get a phrase significance (instead of a single term, doing a multi term significance) would be nice. In the blog post, a similar effect is obtained by highlighting the terms that are identified as significant.But it would be nice to just look at the buckets and determine that.
