if you store the positions for your tokens ( and it is by default if you don't omit them), you have the relative position in the index. [1] I attach a blog post of mine, describing a little bit more in details the lucene internals.
Apart from that, can you explain the problem you are trying to solve ? The high level user experience ? What kind of search/autocompletion/relevancy tuning are you trying to achieve ? Maybe we can help better if we start from the problem :) Cheers [1] http://alexbenedetti.blogspot.co.uk/2015/07/exploring-solr-internals-lucene.html On 9 March 2016 at 15:02, elisabeth benoit <elisaelisael...@gmail.com> wrote: > Hello Alessandro, > > You may be right.
