I was wondering if it is possible to sort by the order that you request documents from SOLR. I am running a In based query and would just like SOLR to return them based on the order that I ask.
In (4,2,3,1) should return me documents ordered 4,2,3,1.
Thanks.

You can easily apply sorting with QueryOptions and field sort (ExtraParams property - I am sorting by savedate field, descending):
var results = _solr.Query(textQuery,
new QueryOptions
{
Highlight = new HighlightingParameters
{
Fields = new[] { "*" },
},
ExtraParams = new Dictionary<string, string>
{
{"fq", dateQuery},
{"sort", "savedate desc"}
}
});

You need Sorting in solr, to order them by field.
I assume that "In based query" means something like: fetch docs whose fieldx
has values in (val1
,val2
). You can a field as multi-valued field and facet on that field. A facet query is a 'is in' search, out of the box (so to say) and it can do more sophisticated searches too.
Edited on OP's query:
Updating a document with a multi-valued field in JSON here. See the line
"my_multivalued_field": [ "aaa", "bbb" ] /* use an array for a multi-valued field */
As for doing a facet query, check this.
You need to do one or more fq statements:
&fq=field1:[400 to 500]
&fq=field2:johnson,thompson
Also do read up on the fact (in link above) that you need to facet on stored rather than indexed fields.
