Michael Gibney commented on SOLR-10894: --------------------------------------- I think this is addressed by https://github.com/apache/solr/pull/1781 -- feedback welcome! Notably, the proposed solution does _not_ modify other special characters (aside from {{"}} double-quote). This should be ok because we're really escaping according to the "streaming expression" syntax, which is a kind of wrapper around the standard query-parsing syntax. In the streaming-expression context, {{q=[some_query]}}, [some_query] may be quoted at the streaming-expression-syntax level, to clarify the boundaries of the `q` param, or unquoted (if quotes are not necessary to clarify the boundaries of the query). In either case, the q param query (exclusive of streaming-expression-param boundary quotes) may itself contain quotes. It is these quotes -- the quotes contained in the q param query _per se_ -- that must be escaped; and a distinction must be made between such double-quote chars at the top-level vs. already-escaped inner double-quote chars. > 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 > Components: streaming expressions > Reporter: Houston Putman > Priority: Major > Attachments: SOLR-10894.patch > > Time Spent: 20m > Remaining Estimate: 0h > > 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. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@solr.apache.org For additional commands, e-mail: issues-h...@solr.apache.org
