Summary0003030: back slash in search string not escaped

I have to type in "\" in the search text box to search for "\"

Steps To Reproduce

try to search for any string with one "\" in it
you won't get anything if there is only one "\" in your search string, if you manually escape the "\" (-->"\"), the search will work

TagsNo tags attached.

In 0.18.0a3, this seems to be an mysql problem.. (The query is properly escaped towards mysql, but there are no results).

according to MYSQL manaul.html:

Note: Because MySQL uses the C escape syntax in strings (for example, \n'), you must double any\' that you use in your LIKE strings. For example, to search for \n', specify it as\n'. To search for \', specify it as\\' (the backslashes are stripped once by the parser and another time when the pattern match is done, leaving a single backslash to be matched).

I you search for \ you will get the following queries to MySql. (At least I get them on my server)

5 SELECT .... ((summary LIKE '%\%') OR (mantis_bug_text_table.description LIKE '%\%') OR (mantis_bug_text_table.steps_to_reproduce LIKE '%\%') OR (mantis_bug_text_table.additional_information LIKE '%\%') OR ( LIKE '%\%') OR (mantis_bugnote_text_table.note LIKE '%\%')) AND ( = mantis_bug_table.bug_text_id)

The backslash is doubled in the query as it should for security.. But after reviewing the mysql manual this is not enough in the LIKE query..

\, % and need an extra \ before.. because \ \% en _ (\\, \\% and \_ after encoding) are escapes for literal \ % and in queries..
(These are parsed after the initial \ parsing of queries)

If it was documented, you might treat is as a feature to allow full LIKE expressions in searching Mantis, but i think it should be fixed for ease of use ;-)
