Hi,=0A=A0=0AI am using Lucene 4.7.2 and my primary use case for Lucene is t=
o do three things: (a) search, (b) sort by a number of fields for the searc=
h results, and (c) facet on probably an equal number of fields (probably th=
e most standard use cases anyway).=0A=0ALet us say, I have a corpus of more=
 than a 100m docs with each document having approx. 10-15 fields excluding =
the content (body) which will also be one of the fields. Out of 10-15, I ha=
ve a requirement to have sorting enabled on all 10-15 and the facets as wel=
l. That makes a total of approx. ~45 fields to be indexed for various reaso=
ns, once for String/Long/TextField, once for SortedDocValuesField, and once=
 for FacetField each.=A0=0A=0AWhat will be the impact of this on the indexi=
ng operation w.r.t. the time taken as well as the extra disk space required=
? Will it grow linearly with the increase in the number of fields?=0A=0AWha=
t is the impact on the memory usage during search time?=0A=0A=0AI will atte=
mpt to benchmark some of these, but if you have any experience with this, r=
equest you to share the details. Thanks,=0A=0A-----------------------=0ATha=
