search query escape function

[ergo]

would it make sense to make an escape function for raw data used in searches and include it within lib itself?

something like this

def solr_escape(input):
    special_chars = ["\\", '+', '-', '&&', '||', '!', '(', ')', '{', '}', '[', ']',
                  '^', '"', '~', '*', '?', ':']
    for char in special_chars:
        if char in input:
            input = input.replace(char, '\\' + char)
    return input

Yes. The search query ought to be escaped, though I would prefer a regexp like this one:

import re
def solr_escape(value):
    ESCAPE_CHARS_RE = re.compile(r'(?<!\\)(?P<char>[&|+\-!(){}[\]^"~*?:])')
    return ESCAPE_CHARS_RE.sub(r'\\\g<char>', value)

[thomasbilk]

So.

@thomasbilk, @ergo: take a look at solrq. It escapes queries for you and also has some other nice features. It can be used with pysolr or any other python solr client.

Please note that / is also a reserved character since Lucene 4.
