java - Search Lucene in decreasing order of doc Id -


i hope can me.

i have index tens of thousands of documents. each document consists of several fields texts , field id (integer). search provides list of ids.

to save resources, maximum number of search results limited 10000. works well. case occurred, in more 10000 results found. let's 15000. lucene search default in increasing order of docids, lucene delivers first 10000 ids.

i find better if lucene provides last 10000 ids , newer documents found. there way change lucene search in decreasing order?

just create sort sorts document id in inverse order.

sort sort = new sort(    new sortfield(       null,                    // or specify field       sortfield.type.doc,        true    ) );

and search top, err, bottom 10k docs:

indexsearcher.search(query, 10000);

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
