Hi,
I need suggestion on solr Autocomplete for Full content with Filter query.
I have currently implemented this as below
1. Solr version 3.6.1
2. solr.StandardTokenizerFactory
3. EdgeNGramFilterFactory with maxGramSize="25" minGramSize="1"
4. Stored the content field
5. Use the Fastvectorhighter and breakiterator on WORD to return results
based on standard analyzer with a fragsize of 20 &using the fq param as
required
This seems to provide snippets ,but they seem like junk at times and not
really relevant as they are pieces of sentence with search term in them .It
could be like
the <keyword> and ...eg: on searching river suggestion is - the river and
...which does not really make sense as a suggestion...
So other options of
- facets support fq but cannot be used for fullcontent tokenized text
due to performance issue
1. Can we use a tool that can just extract keywords/phrases from the
Full content and that can either be indexed or updated to Db and same can
be used to serve the autocomplete?
2. Any other methods?
3. Are there any opensource tools for keyword extraction? Sematext has a
commercial tool for the same.
4. Which would be better for Autocomplete - DB / Index in terms of
speed /performance?
Any pointers?
Regards,
Sujatha
