One way to implement this would be with a "SpanFirstQuery" but I
don't beleive there are any QParsers in Solr (out of hte box) that produce
SpanFirstQueries, so you'd have to customize.
An alternative appraoch that people have been doing since long before Span
Queries have existed, is to index a special marker token (that won't
ever appera in your text) at the begining of your field values, and then
search for a slopy phrase containing your marker token and the word your
user is looking for -- because sloppy phrase queries inherently score
documents higher the closer the terms are to eachother
So if you choose $^$^$ as your marker token, your three sentences would
become...
1: $^$^$ bomb blast in kabul
2: $^$^$ kabul bomb blast
3: $^$^$ 3 people killed in serial bomb blast in kabul
And your query would be something like "$^$^$ kabul"~1000
