Facet counts for common terms of the searched field
I have a requirement. If I search for text field let's say "metal:glass" what
i want is to get the facet counts for all the terms related to "glass" in my
search results.
window(100) since a window can be glass.
plastic(10) plastic is a material just like glass
Iron(10)
Paper(15)
Can I use MLT to get this functionality.Please let me know how can I achieve
this.If possible an example query.
Thanks,
Raju

I mean you can sort the facet results by frequency, which happens to
be the default behavior.
Here is an example field for your schema:
<field name="textfieldfacet" type="string" indexed="true"
stored="true" multiValued="true" />
Here is an example query:
http://localhost:8983/solr/select?q=textfield:copper&facet=true&facet.field=textfieldfacet&facet.limit=5
This will give you the top 5 words in the textfieldfacet.

Thanks Matt for your reply.
What do you mean by frequency(the default)?
Can you please provide an example schema and query will look like.

You may have to take care of this at index time. You can create a new
multivalued field that has minimal processing. Then at index time,
index the full contents of textfield as normal, but then also split it
on whitespace and index each word in the new field you just created.
Now you will be able to facet on this new field and sort the facet by
frequency (the default) to get the most popular words.

Does anybody have answer to this post.I have a similar requirement.
Suppose I have free text field say
I index the field.If I search for textfield:copper.I have to get facet
counts for the most common words found in a textfield.
ie.
example:search for textfield:glass
should return facet counts for common words found textfield.
semiconductor(10),iron(20), silicon (25) material (8) thin(25) and so on.
Can this be done using tagging or MLT.
Thanks,
Sachin
