java - Lucene 4.10 Date Range Query Api -


i want build range query date field programmatically in lucene 4.10, didn't find anyway that. pseudocode be:

new daterangequery(datelowerbound, dateupperbound);

is idea use org.apache.lucene.document.datetool class transform , use numericrangequery?

i'd pick 1 of 2 possibilities:

1 - use datetools obtain string representation indexing:

string indexabledatestring = datetools.datetostring(thedate, datetools.resolution.minute); doc.add(new stringfield("importantdate", indexabledatestring, field.store.yes)); ... topdocs results = indexsearcher.search(new termrangequery(     "importantdate",     new bytesref(datetools.datetostring(lowdate, datetools.resolution.minute)),     new bytesref(datetools.datetostring(highdate, datetools.resolution.minute)),     true,     false )); ... field datefield = resultdocument.getfield("importantdate") date retrieveddate = datetools.stringtodate(datefield.stringvalue());

2 - skip date tools, , index dates numeric values using date.gettime() or calendar.gettimeinmillis(), or similar:

long indexabledatevalue = thedate.gettime(); doc.add(new longfield("importantdate", indexabledatevalue, field.store.yes)); ... topdocs results = indexsearcher.search(numericrangequery.newlongrange(     "importantdate",     lowdate.gettime(),     highdate.gettime(),     true,     false )); ... field datefield = resultdocument.getfield("importantdate") date retrieveddate = new date(datefield.numericvalue());

i'd opt first, makes control on precision more obvious, whichever strikes fancy should work fine.

also worth mentioning solr's triedatefield, though wouldn't recommend getting if aren't using solr anyway.

ruby - How do I merge two hashes into a hash of arrays? -

http://codepad.org/wmyzqlis i'd merge these 2 arrays: a = { :a => 'a', :b => 'b', :d => 'd' } b = { :a => '1', :b => 'b', :c => 'c' } into hash looks this: {:a => ["a", "1"], :b => ["b", "b"], :c => [nil, "c"], :d => ["d", nil] } this doesn't work: p a.merge(b) { |k, v1, v2| [v1, v2] } # {:c=>"c", :a=>["a", "1"], :b=>["b", "b"], :d=>"d"} it's because hash#merge call block duplicate keys. a = { :a => 'a', :b => 'b', :d => 'd' } b = { :a => '1', :b => 'b', :c => 'c' } hash[(a.keys|b.keys).map { |key| [key, [a.fetch(key, nil), b.fetch(key, nil)]] }] # => {:a=>["a", "1"], :b=>["b", "b"], :d=>["d", nil], :c=>...
