Neo4j. Dynamic query with multiple filters on nodes

问题


I have nodes like this and I need apply filter to them 

{
  "value": "ma",
  "object_field_id": 2293
}

{
  "value": 2,
  "object_field_id": 2294
}

MATCH (:UserData {user_id:19})-[:CARD]-(c:Card)-[:FIELD_GROUP]-()-[:FIELD]-(fi:Field) 
WHERE fi.object_field_id IN [23,24] 
  AND (fi.value=~('(?iu).*149.*') 
  AND fi.value=~('(?iu).*gb.*')) 
RETURN c

but it doesn't work with AND

Where is my mistake?

UPD:

Here is query that works but only in one side by FieldUserGroup

MATCH (c:Card)-[:FIELD_GROUP]-()-[:FIELD]-(fi:Field) where (any(prop in keys(fi) where fi[prop] =~ '(?iu).*tom.*'))
return c

I cleaned up your Cypher queries to create the database, hopefully I didn't make any mistakes. You will notice that I removed all of the WITH count(*) as dummy as they are not needed and only cause errors. For the statements that have both MATCH and CREATE they needed a WITH. I reordered and grouped similar statements so that they can all be done in one statement, e.g. end with ;. 

CREATE (:UserData {user_id: 19});

MATCH (n:UserData {user_id: 19})
WITH n
CREATE (n)-[:CARD]->(:Card {name: "card"});

CREATE (:FieldUserGroup {data_id: 1290})

The original query 

MATCH (:UserData {user_id:19})-[:CARD]-(c:Card)-[:FIELD_GROUP]-()-[:FIELD]-(fi:Field) 
WHERE fi.object_field_id IN [23,24] 
  AND (fi.value=~('(?iu).*149.*') 
  AND fi.value=~('(?iu).*gb.*')) 
RETURN c

is working correctly when it returns no records. This is because there are no nodes that match this part of the query

MATCH (fi:Field) 
    WHERE fi.value=~('(?iu).*149.*')  
    RETURN fi;

which also returns no records. The AND clause is working as it should.
