One way to do it would be to use dismax request handler at query time, with a
pf paramater on the same field(s) as your qf paramter, but with a big boost on
the pf. http://wiki.apache.org/solr/DisMaxRequestHandler
I'm not sure why you're getting matches for "tigers" and "woods" on "tiger
woods" though; your example has the EnglishPorterFilterFactory commented out,
if you had that actually in there that would explain it but as it is, I'm not
sure what does. Your synonyms file? That seems odd.
If you WERE using stemming, but wanted un-stemmed results to rank higher, one
way to do it would be to actually use two different solr fields, one stemmed
and one not stemmed. And then again use dismax, and boost the un-stemmed field
higher, in either both qf and pf, or just pf.

Subject: Query related question
Hi All,
When I query for a word say Tiger woods, and sort results by score... i do
notice that the results are mixed up i.e first 5 results match Tiger woods
the next 2 match either tiger/tigers or wood/woods
the next 2 after that i notice again match tiger woods.
How do i make sure that when searching for words like above i get all the
results matching whole search term first, followed by individual tokens like
tiger, woods later.
My text fieldtype defined as follows
<fieldType name="text" class="solr.TextField" positionIncrementGap="100">
<analyzer type="index">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<!--<filter class="solr.EnglishPorterFilterFactory"
protected="protwords.txt"/>-->
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
<analyzer type="query">
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
<filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt"
ignoreCase="true" expand="true"/>
<filter class="solr.StopFilterFactory" ignoreCase="true"
words="stopwords.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
<!--<filter class="solr.EnglishPorterFilterFactory"
protected="protwords.txt"/> -->
<filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
</analyzer>
</fieldType>
Thanks
Indrani
