get term frequency, just only keywords search
I need to get the TermFrequency in Solr4 but just about my keywords search
and not for all the keywords that a field cointains.
I try to explain with an example:
I have this fiels:
when I try to searh into field "foods" the keyword "pizza" like this:
http://localhost:8983/solr/mycore/select?q=pizza&fl=id&tv=true&df=foods&tv.tf_idf=true&tv.tf=true&tv.df=true&tv.fl=foods&omitHeader=true&defType=dismax
this is my results:
1
id
1
5
3
1.6667
2
3
0.
2
1
2.0
Now, my question is: why I get the tf for all the indexed keywords into
field foods and not only for my keyword search ("pizza")?
Please, have you any suggests? Thanks in advance

RE: get term frequency, just only keywords search
Thanks for your answer, but I'm tring to use TermsComponent but the output is similar. TermsComponent returns all the terms (*and not just for the term that I have search*) and their counts for a given field. something wrong? -- View this message in context: http://lucene.472066.n3.nabble.com/get-term-frequency-just-only-keywords-search-tp4084510p4084518.html Sent from the Solr - User mailing list archive at Nabble.com.

RE: get term frequency, just only keywords search
sorry, but now I give more attention at the results and it don't return that I needed. If I have two documents indexed: the text of my first document: "ice-cream pizza pizza pizza" the text of my second document: "pizza tomato" it returns the followed code: 1 3 2 *I want that it returns 3 for the first document and 1 for the second document and not 2* Thanks a lot -- View this message in context: http://lucene.472066.n3.nabble.com/SOLVED-get-term-frequency-just-only-keywords-search-tp4084510p4084530.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: get term frequency, just only keywords search
Thanks Jack, I'm tring to use tf function but I don't understand: why he returns a float value and not integer? At the start of this topic I explained an example where I used term Frequency but it don't works how I need because he returns the term frequency about all the terms of my field.

Re: get term frequency, just only keywords search
Thanks. I tried to use termfreq function and it is ok for me but, last my question is: if I have a query like this: q="pizza"+"tomato"&fl=id,termfreq(myfield,**) how set my query (pizza+tomato) in second param in termfreq function? -- View this message in context: http://lucene.472066.n3.nabble.com/get-term-frequency-just-only-keywords-search-tp4084510p4084643.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: get term frequency, just only keywords search

Re: get term frequency, just only keywords search
there isn't a way to get termFreq about a search like "french fries" (sentence)? -- View this message in context: http://lucene.472066.n3.nabble.com/get-term-frequency-just-only-keywords-search-tp4084510p4085454.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: get term frequency, just only keywords search
ok I undestand it (thanks) but if I search a sentence and type "debugQuery=on", in the explain I obtain termFreq=2.0 and it right. Is it possible to obtain that parameter? -- View this message in context: http://lucene.472066.n3.nabble.com/get-term-frequency-just-only-keywords-search-tp4084510p4085464.html Sent from the Solr - User mailing list archive at Nabble.com.

Re: get term frequency, just only keywords search
Thanks a lot guys, @Jack in my search I use dismax (how defType) and I search either term or phrase, but I need to get the number that show me how many time that term or phrase is in the document. I could get it from debugQuery but I would like get it directly from the results. What do you suggest?

Change the score of a document based on the *value* of a multifield using dismax
Hi guys,
I need to change the score of a document based on the value of a multifield.
I thoght that maybe I need to set boost in index-time (but I don't sure).
Now I explain you my situation:
- I'm usng solr4.4
- I'm index data using dataimporthandler with rdbms
- my documents are a particular kind of places
- my field are places and their review and description
- my multifield is distance_place beacause each place (one place is a field)
has a lot of review or description
I'm tring with the following request but it return error "can not use
FieldCache on multivalued field: distance_place"
http://localhost:8983/solr/myCore/select?q={!boost b=distance_place v=$qq
defType=dismax}&qq=pizza&fl=*,score&qf=text_review+text_description
I'm thinking that if I set the boost at each review/description with the
value of the distance_place in index-time it is easy, but in this case I
don't know which is the right syntax to set the boost into db-dataimport.xml
file.
Please, Any suggests?
Thanks in advance.

Re: Change the score of a document based on the *value* of a multifield using dismax
Ok, agree. I mean that I want to set a boost to each review/description (multifield) of the Places (multifield), and this boost is the corrispective value of the distance beetween the place and the particular kind of place that I have as document. Is it clear? I Try to explain again the situation: - my document is a particular kind of Place (for example airport) - my fields are all the text (review and description) of the places around the airport having a distance < 10 km. Now if I search for "pizza" solr return me the airport where there are a lot of terms "pizza" into review/description doesn't consider the distance. So I want to set a boost at each review/description based on the value of distance.

Re: Change the score of a document based on the *value* of a multifield using dismax
Thanks Erick, but think if I have an simple float value and not distance.
I have a situation like this:
- id: 1
- myText: ["iphone", "ipad", "macbook"]
- myFieldFloat: [3.4,2.1,5.3]
I want to set the value of myFieldFloat at his respective myText.
I tried this:
but it return an error:
org.apache.solr.handler.dataimport.DataImportHandlerException: Data Config
problem: For input string: "{$places.distance_place}"
at
I also tried to set in my query a Cast, but the same error:
SELECT myText,
CAST(myFloatValue AS DECIMAL(10,6)) as myFloatValue
FROM myTable
WHERE myCondition
please, any suggests?
