how to search negative number in solr?

Question

In solr I want to search one field with negative number like nodeId:-1. in schema.xml, I defined it like this: <field name="nodeId" type="int" indexed="true" stored="true" />

solr throws error when use "nodeId:-1" to search like this: org.apache.lucene.queryParser.ParseException: Cannot parse 'storeId:-1': Encountered " "-" "- "" at line 1, column 8. Was expecting one of: "(" ... "*" ... ... ... ... ... "[" ... "{" ... ...

I must search with storeId:\-1 or storeId:"-1" to get answer.

now the question is : Can I modify any solr configration files to search without any escape characters? Or another way to resolve this problem without modify java code. Thanks.

I personally think escaping properly inside your Java code is the better way. ClientUtils.escapeQueryChars would be the method of choice.
