So I will have a solr field that contains years, ie, 1990, 2010,
maybe even 1492, 1209 and 907/0907.
I will be doing range limits over this field. Ie, [1950 TO 1975] or
what have you. The data represents publication dates of books on a
large library shelves; there will be around 3 million
This isn't a very worrisome case. Most of the messages you see on the board
about
the dangers of dates arise because dates can be stored with many unique
values if
they include milliseconds. Then, when sorting on date your memory explodes
because
all the dates are loaded into memory.
In your
There is no 'trie string'.
If you use a trie type for this problem, sorting will take much less
memory. Sorting strings uses memory both per document and per unique
term. The Trie types do not use any memory per unique term. So, yes, a
Trie Integer is a good choice for this problem.
