-------------------------------------
Summary: Streaming expressions handling of escaped special
characters bug
Key: SOLR-10894
URL: https://issues.apache.org/jira/browse/SOLR-10894
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Houston Putman
Streaming expressions expect all special characters in named parameter values
to be singly escaped. Since queries can contain strings surrounded by double
quotes, double-escaping is necessary.
Given the following query:
{{summary:"\"This is a summary\"\+"}}
A streaming expression would require surrounding the query with double quotes,
therefore every special character in the query should be escaped:
{{select(collection,q="\"\\\"This is a summary\\\"\\\+\"",....)}}
Streaming expressions should unescape the strings contained within double
quotes, however currently they are only unescaping {{\" -> "}}. Therefore it is
impossible to query for text fields containing double quotes. Also other
special characters are not unescaped; this inconsistency causes confusion.
