wildcards don't work on strfields

[romanchyla]

did not expect this: reader:X02f794aca returns results, but reader:X02f794ac* doesn’t. Are wildcard searches disabled for this field? And if so, are there other fields where they are not allowed?

it is a string field -- so in those it doesn't make much sense to use wildcards, but it should be possible -- the same thing happens with a facet field; but in there prefix query will work

looks like something is wrong: either some misconfiguration so that lucene cannot fetch proper binary representation of the tokens to search for or maybe the parser doesn't treat it as a wildcard search - and treats * as a literal
until i know what it is, you can use the following: http://adsabs.harvard.edu/solr/collection1/select?indent=on&q={!prefix%20f=reader}X02f794a&wt=json
