I apologize, entering the defType parameter explicitly has nothing to do
with it, this was a caching issue. I tested the different configurations
thoroughly, and this is what I've come up with:
- When using 'dismax' request handler as default:
- Queries are always parsed using the dismax parser, whether I use
qt=standard, qt=dismax, or qt=. It _does_ use the correct request handler,
because the echo'd params are correct for that handler. However, it seems to
always be using defType=dismax. I can tell this because when I use the
parameter debugQuery=true, I can see that it is creating a
DisjunctionMaxQuery.
- When using 'standard' request handler as default:
- The behaviour is as expected. When I enter no qt parameter or
qt=standard, it uses the standard request handler and doesn't use dismax for
the defType. When I use qt=dismax, it uses the dismax request handler and
dismax for the defType.
So the problem is when setting the default request handler to dismax, it
always uses defType=dismax (even though it uses the 'standard' request
handler). defType=dismax does not show up in the echo'd parameters, but I
can tell by using debugQuery=true (and the fact that I get no results when I
specify a field).
Can someone try reproducing this using the configuration I specified in my
first post? Sorry again for being confusing, I got sidetracked by the
caching issue.
