postgresql - Partial text search with postgreql & django -

-

tried implement partial text search postgresql , django,used following query

entry.objects.filter(headline__contains="search text")

this returns records having exact match,ie suppose checking match against record "welcome new world" query __contains="welcome world" , returns 0 records

how can implement partial text search postgresql-8.4 , django?

if want exact partial search can use startswitch field lookup method: entry.objects.filter(headline__startswith="search text"). see more info @ https://docs.djangoproject.com/en/dev/ref/models/querysets/#startswith.

this method creates query ("select ... headline 'search text%'") if you're looking fulltext alternative can check out postgresql's built in tsearch2 extension or other options such xapian, solr, sphinx, etc.

each of former engines mentioned have django apps makes them easier integrate: djapian xapian integration or haystack multiple integrations in 1 app.

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
