Hi Sergio,
assuming that you don't want to disable tokenisation (otherwise you can
define the indexed field as a string and search it as a whole),
in "Relevant Search" the authors describe a cool approach using the so
called "Sentinel Tokens", which are symbolic tokens representing the
beginning and the end of a value (field value or query).
SENTINEL_BEGIN<value>SENTINEL_END
Those tokens could be injected at index and query time so the returned
matches will be effectively "exact" matches. Matching docs will have
exact values matching (that actually depends on the text analysis you
apply) and the sentinels in the expected place (beginning + end)
Best,
Andrea

Hi,
I have to search for company names where my first requirement is to find
only exact matches on the company name.
For instance if I search for "CENTURY BANCORP, INC." I shouldn't find "NEW
CENTURY BANCORP, INC."
because the result company has the extra keyword "NEW".
I can't use exact match because the sequence of tokens may differ. Basically
I need to find results where the tokens are the same in any order and the
number of tokens match.
I have no idea if it's possible as include in the query the number of tokens
and solr field has that info within to match it.
Thanks for your help
Sergio
