Hi,
Fixed the issue with document and formatting.
My schema is like below.
<fields> <dynamicField name="Subject-Name-*" type="string"
indexed="true" stored="true"/> <dynamicField
name="Subject-Mark-*" type="int" indexed="true" stored="true"/> </fields>
My need is to search only three subject fields and boost those subjects which
has a higher Mark(Mark can be in between 1 - 10).
Again Top subjects will get a higher boost than preceding one's.
Like if a search term is present in Subject-Name-1,Then it will get a higher
boost than Subject-Name-2 and Subject-Name-3.
Similarly Subject-Mark-1 will get higher boost than Subject-Mark-2 and
Subject-Mark-3.
To achieve this i am querying over subject fields and my query looks like
below.
q=+Economics+Geography&wt=xml&deftype=edismax&qf=Subject-Name-1+Subject-Name-2+Subject-Name-3&bq=Subject-Name-1%3AEconomics%3BGeography^50.0+Subject-Mark-1%3A20^90.0+Subject-Mark-1%3A9^80.0+Subject-Mark-1%3A8^70.0+Subject-Mark-1%3A7^60.0+Subject-Name-2%3AEconomics%3BGeography^45.0+Subject-Mark-2%3A20^90.0+Subject-Mark-2%3A9^80.0+Subject-Mark-2%3A8^70.0+Subject-Mark-2%3A7^60.0+Subject-Name-3%3AEconomics%3BGeography^40.0+Subject-Mark-3%3A20^90.0+Subject-Mark-3%3A9^80.0+Subject-Mark-3%3A8^70.0+Subject-Mark-3%3A7^60.0
If i am having four documents like below
<doc> <str name="Subject-Name-1">Economics</str> <str
name="Subject-Name-2">Geography</str> <str
name="Subject-Name-3">History</str> <int name="Subject-Mark-1">7</int>
<int name="Subject-Mark-2">7</int> <int name="Subject-Mark-3">6</int>
</doc>
<doc> <str name="Subject-Name-1">Economics</str> <str
name="Subject-Name-2">History</str> <str
name="Subject-Name-3">Geography</str> <int name="Subject-Mark-1">8</int>
<int name="Subject-Mark-2">8</int> <int name="Subject-Mark-3">5</int>
</doc>
<doc> <str name="Subject-Name-1">Economics</str> <str
name="Subject-Name-2">History</str> <str
name="Subject-Name-3">Geography</str> <int name="Subject-Mark-1">9</int>
<int name="Subject-Mark-2">6</int> <int name="Subject-Mark-3">7</int>
</doc>
<doc> <str name="Subject-Name-1">Economics</str> <str
name="Subject-Name-2">Mathematics</str> <str
name="Subject-Name-3">History</str> <int name="Subject-Mark-1">7</int>
<int name="Subject-Mark-2">7</int> <int name="Subject-Mark-3">6</int>
</doc>
then i am getting a higher score for last document which has only one of the
search term !!!
But in my situation it is not applicable. My requirement is,if a document has
only one term then they should get a lower score than the documents which are
having both of the terms.
Is it happening because of idf(rarer terms give higher contribution to the
total score) ?
Or there is something wrong with my query ?
Can anybody help me to achieve the desired output.
Thanks in advance
