Re: How to Boost
I got it:
To add an array of var to an anonymous type add them like this.
var field1 = new {field=Name^20};
var field2 = new {field = _all};
var field3 = new {field = Id^20};
var myfields = new [] {field1,field2};
This is slick now it puts the brackets in and there is no escaping :-)

I have an anonymous type doing a match all query and this works fine and
dandy.
I am trying to do the multi_match as above but it isn't returning any
results. I'm not sure
var myfields = [\Name#94;20\,\Id#94;20\,\_all\]; - this gets
no results
var myfields = [\Name^20\,\Id^20\,\_all\]; - this crashes with
all kinds of errors
How do you do these bracketed values?
var search = new
{
query = new
{
multi_match = new
{
fields = myfields,
query = keyword,
type = best_fields,
use_dis_max= true
}
},
from = 0,
size = limitAllTypes,
aggs = new
{
top_types = new
{
terms = new
{
field = _type
},
aggs = new
{
top_type_hits = new
{
top_hits = new
{
size = limitPerType
}
}
}
}
}
};

add a boost directly to the name and id fields. Something like:
{
multi_match: {

query: keyword,

}
That tells Elasticsearch to search all fields, but to additionally search
name and id and double their score if they match (that's the ^2 part).
the best_fields type will use the best score from the name, id, and _all
searches. You might want most_fields to rank records that contain your
query terms in name *and* id *and* other fields even higher. Note that
my snippet is using the Query DSL. The syntax for the client you're using
will probably be slightly different but that's the general idea.
Also note that I've been using Elasticsearch less than a year though so
there may be better approaches, but that's where I'd start.

I'm using ElasticSearchClient and sending this search.

How do i tell this to boost the name and id fields over all other fields.
If I'm searching for My Searched Company and that is in the Name field
I want it at the top of the list. vs in notes, addresses or whatever other
