These methods look promising in terms of ease of use of
FunctionscoreQuery but they dont exist in Lucene 6.6.0.
static FunctionScoreQuery boostByQuery(Query in, Query boostMatch,
float boostValue)
Returns a FunctionScoreQuery where the scores of a wrapped query are
multiplied by a boost factor if the document being scored also matches
a separate boosting query.
static FunctionScoreQuery boostByValue(Query in, DoubleValuesSource
boost)
Returns a FunctionScoreQuery where the scores of a wrapped query are
multiplied by the value of a DoubleValuesSource.

i have one MultiFieldQueryParser based Query and one BooleanQuery
with dynamic number of TermQuery's.
i dont have SortField objects. Are there examples with the above
query types please?

Robert,
thanks, this is helpful but why did this change when it was great to
use? SortField is a new concept to me and i am not sure this is
avail in 6.6.0 but will check.
This new way seems more tricky.
if there are more examples, i will be happier :)
Best regards

setBoost
@Deprecated
public void setBoost(float boost)
Deprecated. Index-time boosts are deprecated, please index index-time
scoring factors into a doc value field and combine them with the
score at
query time using eg. FunctionScoreQuery.
Sets the boost factor on this field.
Throws:
IllegalArgumentException - if this field is not indexed, or if it
omits
norms.
See Also:
boost()
Any example on how to use FunctionScoreQuery? How will this affect
the
IndexWriter?
