Subject Solr performance: multiValued filed vs separate fields
Date Thu, 15 May 2014 14:29:35 GMT
I wonder about performance difference of 2 indexing options: 1- multivalued
field 2- separate fields

The case is as follows: Each document has 100 “properties”: prop1..prop100.
The values are strings and there is no relation between different
properties. I would like to search by exact match on several properties by
known values (like ids). For example: search for all docs having
prop1=”blue” and prop6=”high”

I can choose to build the indexes in 1 of 2 ways: 1- the trivial way – 100
separate fields, 1 for each property, multiValued=false. the values are
just property values. 2- 1 field (named “properties”) multiValued=true. The
field will have 100 values: value1=”prop1:blue”.. value6=”high” etc

Is it correct to say that option1 will have much better performance in
searching? How about indexing performance?
