Lucene Full Text search & Starts With on Neo4j & REST?

[elado]

Is there a way to query Neo4j's Lucene with a "starts with" query, in REST? (For an autocomplete purposes). I can put a token string (say, <start_token>) at the beginning and query for <start_token>word*, but that's ugly. Any suggestions?

Hi elado

which version did you use ?

Perhaps I have not understood you correctly, but why do you need a start token?

You could just do something like:

<server>/index/node/<indexName>?query=<property>:word*

If I have these indexed strings:

- Lorem ipsum

- Lorem ipsum dolor sit amet

- Ipsum dolor

When I search for ipsu* it'll fetch them all. I want to fetch all items that start with ipsum (only the third).

Thanks.

Weird, cos my autocomplete does a starts with, and does not return substring matches like the example you mentioned below. Need to check my code again

Did you use an fulltext index for indexing the strings?

An exact index doesn't break them down into the individual parts, a fulltext index does.

Yes, that was it. I didn't notice that Elado was using a full text index- my bad!

So you may need to use a PrefixQuery.
I guess you may need to write a script for this (someone correct me if there is a better way)- example: http://docs.neo4j.org/chunked/stable/gremlin-plugin.html#rest-api-send-an-arbitrary-groovy-script---lucene-sorting
