Hi,

SDN finder method is failing with REstResultException whenever spaces are
there in parameters.
Here is my use case,
@NodeEntiry
Class User{

*@Indexed(indexName="username", indexType=IndexType.FULLTEXT)*

* String username;*}
Here is my finder function in repository

*User findByusername(String username);*
Here is my finder call,

User user =  userRepo.findByusername("Spring data"); This call throws below
exception...

However, everything works file, when param is just "Spring"

Kindly let me know your suggestions to resolve this.

Exception:

Thanks for the information Michael.
Have another issue with executing Cypher query from SDN.
It works fine, when i executed on neo4j console. Issue is with passing
parameter. Can you please correct me?

@Query( "START n=node:search(\"name:*{brandname}*\") RETURN n")

Iterable<Brand> findBynameSearch(@Param("brandname") String brandname);
Exception is:
exception: org.neo4j.rest.graphdb.RestResultException:
org.apache.lucene.queryParser.ParseException: Cannot parse
'name:*{brandname}*': Encountered " "}" "} "" at line 1, column 16.
Was expecting one of:
    "TO" ...
    <RANGEEX_QUOTED> ...
    <RANGEEX_GOOP> ...

You have to pass in the whole index-query string:

> @Query( "START n=node:search({query}) RETURN n")

> Iterable<Brand> findBynameSearch(@Param("query") String query);

String query = \"name:*"+brandname+"*\"

Hi Michael,

This one is not working with pattern matching.
for example,
START n=node:search("name:\"abdul azeez\"") RETURN n; -- WORKING
START n=node:search("name:*abdul*") RETURN n; -- WORKING
START n=node:search("name:\"*abdul*\"") RETURN n; -- NOT WORKING
START n=node:search("name:\"*abdul azeez*\"") RETURN n; -- NOT WORKING

Is there a way to work while spaces and pattern matching in same query
param?

Thanks,
Abdul

I tried directly on neo4j console itself.

Abdul,
there are several layers of String processing going on, including
Lucene processing the String, try more escapes :)

start n=node:node_auto_index("name:Neo\\\"") return n

I tried in below ways, it throws "Invalid escape sequence"
START n=node:search("name:\*\"abdul azeez\"\*") RETURN n; -- NOT WORKING
START n=node:search("name:\"\*abdul azeez\*\"") RETURN n; -- NOT WORKING

Abdul,
I think you need three \\\ for every escape " and \\ for *, see

START n=node:node_auto_index("name:\\\"\\*abdul azeez\\*\\\"") RETURN n;
