Its not in the docs (atleast from what i've read)...please tell me there's a way around this weird restriction! I can't really think of a way to restructure my app cause the inequality filter is basically a necessity at this point i'd love to be able to sort my results by something other than cost... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

here : http://code.google.com/appengine/docs/python/datastore/queriesandindexes.html#Restrictions_on_Queries check : Properties In Inequality Filters Must Be Sorted Before Other Sort Orders I think that you should do search_query.filter(cost , min_price) search_query.filter(cost , max_price) search_query.order(cost) search_query.order(distance) On Aug 21, 10:58 am, iceanfire iceanf...@gmail.com wrote: I'm getting the following error: BadArgumentError: First ordering property must be the same as inequality filter property, if specified for this query; received distance, expected cost when i run the following code: search_query.filter(cost , min_price) search_query.filter(cost , max_price) search_query.order(distance) Did anyone know about this?

Hi philippe, I did try the code you provided but that doesn't really work--all it does is rank the results in the order of cost. Infact, the result that is furthest away, ends up coming in first place, with the rest randomly scattered. Any other ideas? -thanks On Aug 21, 5:43 am, Philippe philippe.cr...@gmail.com wrote: here :http://code.google.com/appengine/docs/python/datastore/queriesandinde... check : Properties In Inequality Filters Must Be Sorted Before Other Sort Orders I think that you should do search_query.filter(cost , min_price) search_query.filter(cost , max_price) search_query.order(cost) search_query.order(distance) On Aug 21, 10:58 am, iceanfire iceanf...@gmail.com wrote: I'm getting the following error: BadArgumentError: First ordering property must be the same as inequality filter property, if specified for this query; received distance, expected cost when i run the following code: search_query.filter(cost , min_price) search_query.filter(cost , max_price) search_query.order(distance) Did anyone know about this?
