Hi
I am trying to search on URL type field , created a custom analyzer with
tokenizer as uax_url_email , and indexedit with the same.
i have explicitly specified the "index_analyzer" and "search_analyzer"
fields while creating the mapping, as the same custom analyzer.
As per my understanding , the uax_url_email tokenizer , recognizes the
string as an Email or an URL , but does not breaks it further.
So , since the whole string is preserved as a single token , wild card
Queries should work on it.
They do work in some cases like when i search for
www.englishdictionary.fr
but fail when i do a search for www.englishdictionary.fr/hann
and an Parsing Exception is thrown .
Since i have explicitly specified the "search_analyzer" as the custom
analyzer , my query_string is supposed to be analyzed in the way defined in
the analyzer specified., i.e any url will not be tokenized by being broken
into smaller components.
I also checked with the curl Command , to check the fuctioning of the
custom analyzer, and as expected , it's showing me the complete URL as a
single token.
but while searching throgh java API, a parsing exception is being thrown.
I also tried setting the analyzer as "uax_url_email1" (custom analyzer's
name) with the query , and also tried setting analyzeWildcard = false , but
to no avail , still the query fails.
Below is the link for the Gist
https://gist.github.com/F-Torres/5711570
- Please also suggest how to search for wildcards in the URL , if it
already contains wildcard characters like ? and * , ( while keeping the URL
field not analyzed / Keyword Analyzer / Custom Analyzer with uax_url_email
tokenizer )
Exception being thrown : -
