Streaming expressions handling of escaped special characters bug

    Details

      Description

      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.
