Vineeth,
I just saw your response today and I came to the same conclusion yesterday
after you gave me a nice working example! I took it a step further doing
the same grouping by the field that you did and it came out nicely.
Something is sinking in anyways with me..-)
Besides some possible language support issues, the biggest thing I see for
challenges could be if stemming is involved (you search for federal and
hits are returned on federal, federalizing, etc... so if you just look for
federal in the term count, it wouldn't find all the matches) and then
dealing with case sensitivity when looking at the term frequencies (the
user typed in "Federal cases" which matches by default on federal and
cases) it seems you would need to lower case the lookup for the term
frequencies. What do you think about these cases?
Thanks!
Darren

Hello Darren ,
Following query does what you have asked for ( replace FIELD with the
field you are looking for) -
{
"fields": [
"text"
],
"query": {
"term": {
"text": "god"
}
},
"script_fields": {
"tf": {
"script": "_index['FIELD']['cat'].tf()"
}
}
}
For the second one , use -
{
"query": {
"term": {
"FIELD": "CAT"
}
},
"aggs": {
"groupName": {
"terms": {
"field": "GROUP_FIELD"
},
"aggs": {
"catStats": {
"sum": {
"script": "_index['FIELD']['CAT'].tf()"
}
}
}
}
}
}
Thanks

Vineeth,
Thanks for responding. What I am looking for is provided I perform a
search for various terms, how given the search result can I understand the
frequency of the hits within documents. For example, I perform a full text
search on cat. 5 documents are returned. I could today get the terms that
were found highlighted but that is of course quite nasty. Instead what I
would like returned is the documents but something like for each document
saying:
Document 1 (group: 1): cat - 5
Document 2 (group: 2): cat - 3
Document 3 (group: 1): cat - 2
...
Document n - cat - #
Also, there is other metadata that it would be nice to aggregate on too
so I could get an answer for the above scenario:
group : 1 - cat - 7
group : 2 - cat - 3
Thanks
Darren
