search for: default_prefix

Hi, I'm using Xapian in Python2. I'm trying to replicate an analysis that somebody else performed in Lucene. To do that I need to do a search for a multi-word query in which particular fields are boosted - preferably at query time. That is, given a query like "the cat is lying on the mat" (with an OR operator, ignoring word positions but with stemming and stop words removed),

...discusses this, and has sample code in python. I'd read from the beginning, including the core concepts. (https://getting-started-with-xapian.readthedocs.io/). It also shows how to use the QueryParser to split and stem user-inputted queries into Xapian Query objects. You'll want to set the default_prefix when you call QueryParser::parse_query (this is covered in the concepts section of the getting started guide: https://getting-started-with-xapian.readthedocs.io/en/latest/concepts/indexing/terms.html?highlight=default_prefix#fields-and-term-prefixes). You'll end up with python that looks a lit...

I''ve updated to 2.1 and am continuing to have issues with datetime_select helpers which worked fine previously. Example: <% form_remote_tag(:url => { :controller => ''notes'', :action => :add_booking_note_ajax, :id => @booking},

I would like to have a date control on a page and I would like a behavior similar to what you get using date_select with the :include_blank => true option where the first value in the dropdown is "- Month -", "- Day -", or "- Year -" rather than a blank value for the respective month, day, and year select fields. I took a look at the ruby source for
