Hi all!
A little bit more of exploration:)
After indexing with multiple atomic field values, here is what I get:
indexSearcher.doc(0).getFields("gramm")
stored,indexed,tokenized,termVector,omitNorms<gramm:S|3|1000>
stored,indexed,tokenized,termVector,omitNorms<gramm:V|1|1>
stored,indexed,tokenized,termVector,omitNorms<gramm:PR|1|1>
stored,indexed,tokenized,termVector,omitNorms<gramm:S|3|1>
stored,indexed,tokenized,termVector,omitNorms<gramm:SPRO|0|1000 S|1|0>
stored,indexed,tokenized,termVector,omitNorms<gramm:A|1|1>
stored,indexed,tokenized,termVector,omitNorms<gramm:SPRO|1|1000>
stored,indexed,tokenized,termVector,omitNorms<gramm:ADV|1|1>
stored,indexed,tokenized,termVector,omitNorms<gramm:A|1|1>
indexSearcher.doc(0).getField("gramm")
stored,indexed,tokenized,termVector,omitNorms<gramm:S|3|1000>
The values are absolutely correct, but why getField() returns only the first
one instead of concatenating them?
If I want to handcraft my custom highlighter, is iterating through (roughly)
all the stored field values supposed to be the right technique? (Previously I
was using Alanyzer.tokenStream.incrementToken() for the entire concatenated
field.)
