Need a Query syntax for fetching results
Hi ,
I am new to Lucene. I have a requirement where when i request the
organization name, it should show the matching organization names.
I have written the q param as
orgname_text: ABC test
it is returning the result :-
ABC test limited
ABC XYZ limited
DEF ABC limted
test limited
I want all the matching result which starts with either ABC or test. so
here i dont want DEF ABC limited. Please let me know what feature or
syntax i should use to get the required result.
Thanks
Raj

Hi Raj
Maybe this would be what you need.
"Keyword Tokenizer
This tokenizer treats the entire text field as a single token."
There used to be an example showing the use of this in schema.xml, but I am away from my computer so it is hard to check.
And everything Emir says is spot-on.
Then you might want to go further with ngrams or a spelling check so the user need not be perfect.
Cheers -- Rick

Hi Raj,
You need to get familiar with Solr analysis chain: https://lucene.apache.org/solr/guide/6_6/understanding-analyzers-tokenizers-and-filters.html <https://lucene.apache.org/solr/guide/6_6/understanding-analyzers-tokenizers-and-filters.html>
When playing with it, use admin console analysis tab to see what tokens are produced.
And you need to understand your search requirements and cover them with one or more fields. Note that you can use copyField to index the same content in different ways to handle different search requirements.
It is probably not what you want, but based on what you described, you do not care about anything but the first token in your field, so you can use LimitTokenCountFilter to index only the first token. In query analysis you do not use it and with default operator OR you will get what you want.
HTH,
Emir
