Subject: Is there a problem with -Infinity as boost?
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

I am considering using a boost as follows:=20

&boost=3Dlog(qty)

Where qty is the quantity in stock of a given product i.e. qty could be 0,
1, 2, 3, =E2=80=A6 etc. The problem I see is that log(0) is -Infinity. Woul=
d this be
a problem for Solr? For me it is not a problem because=20
log(0) < log(1) < log(2) etc.=20

I'd be grateful for any thoughts. One alternative is to use max e.g.
&boost=3Dmax(log(qty), -1)=20

But still this would cause Solr to compute the -Infinity and then discard
it.  So can I use an expression for boost that would result in =E2=80=93Inf=
inity?=20

Thank you
O. O.
