Proximity search - percentage - more than one result


(janek sendrowski) #1

Hi,

Is there the possibility to specify a percentage value, when performing the
proximity search.

LIKE: "this is an example"~0.5 (This doesn't work)

Furthermore I like to know if there is a way to get the N best results, not
only the best.

Thank you for your answers!

Hey,

the main question is, what does proximity mean for you? Could be several
things

  • Words should be similar to the ones specified (including typos)
  • Words should be exact, but the occurance of each words should be near to
    each other
  • The whole phrase should be similar
  • etc...

You might want to take a look at the fuzzy queries, at phonetic analyzers
and, if you want proximity search like described in
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#_proximity_searches
then you need to specify a number greather than one in order to define the
distance.

hope this helps a bit
