Hello there, this is a very novice question but I'm trying to understand how
boosting certain elements in a document works.
I started with this query,
{"from" : 0,"size" : 6,"fields" : ["\_id"],"sort" : {"\_score":
"desc","vendor.name.stored": "asc","item\_name.stored": "asc"},"query" :
{"filtered" : {"query" : {"query\_string" : {"fields" : ["\_all"],"query" :
"Calprotectin", "default\_operator" : "AND" }},"filter" : {"and" : [{"query"
: {"query\_string" : {"fields" : ["targeted\_countries"],"query" : "All US"}}}
]}}}}
then i needed to boost certain elements in the document more than the others
so I did this
{"from" : 0,"size" : 60,"fields" : ["\_id"],"sort" : {"\_score":
"desc","vendor.name.stored": "asc","item\_name.stored": "asc"},"query" :
{"filtered" : {"query" : {"query\_string" : {"fields" :
["item\_name^4","vendor^4","id\_plus\_name","category\_name^3","targeted\_countries","vendor\_search\_name^4","Additional

"AND" }},"filter" : {"and" : [{"query" : {"query\_string" : {"fields" :
["targeted\_countries"],"query" : "All US"}}} ]}}}}
the query slowed down considerably, am I doing this correctly? Is there a
way to speed it up? Any help is much appreciated
