Unable to understand a part of code

[Sayan Chowdhury]

Hi,

I was studying the code in txcommon/haystack_utils.py, when I came
across this line:
filters.append(SQ(slug='%s^1.2' % w))

I am unable to understand the utility of '^1.2'.

Here's the link to the code:

First off, note that this is related to the django-haystack
SearchQuerySet and not the Django ORM. That's why you might
have got confused.

FWIW for the SOLR search engine we use, when you do a search
in more than one field, you can boost the fields to have different
importance. I.e.:

SearchQuerySet().filter(SQ(slug='foo^1.3') || SQ(name='foo^1.2'))

The line above searches for the keyword 'foo' using two fields, 'slug'
and 'name'. As the field slug has a bigger booster then name,
matches on that field are considered more relevant, coming first in
the search result.

Hope it's clear now. :)
