Re: Searching for words begining with "or"

Just so you know, the presence of a wildcard in a term means that the term will not be analyzed. So, state:OR* should fail since "OR" will not be in the index - because it would index as "or" (lowercase). Hmmm... why does "or" seem familiar...? Ah yeah... right!... The standard analyzer in

Re: Partial word match using n-grams

There are several options: As Allison suggested, pad your words with ##, so that "quota tom" becomes "##quota## ##tom##" at indexing time, and the query "quota to" becomes either "##quota ##to", or if you want to optimize, only pad query terms < 3 characters, so it becomes "quota ##to". That shoul

Re: Searching for words begining with "or"

When I make my query, everything goes well until I add the last part : (city:or* OR state:or*). I tried the first solution that was given to me but putting \OR and \AND doesn't seem to be the solution. The query is actually well built, he has no problem with OR or \OR to parse the query since the q

Re: Searching for words begining with "or"

Break your query down into simpler pieces for testing. What pieces seem to have what problems? Be specific about the symptom, and how you "know" that something is wrong. You wrote: stored,indexed,tokenized,omitNorms>. But... the standard analyzer would have lowercased that term. Did it, or are

Searching for words begining with "or"

Hi everyone, I am new to this forum, I have made some research for my question but I can't seem to find an answer for it. I am using Lucene for a project and I know for sure that in my lucene index I have somewhere this document with these elements : Document stored,indexed,tokenized,omitNorms st

RE: Partial word match using n-grams

Thanks for the reply Tim. I really should have been clearer. Let's say I have an object named "quota_tommy_1234". I'd like to match that object with any 3 character (or more) substring of that name. So for example: quo tom 234 quota etc. Further, at search time I'm splitting input on white

RE: Partial word match using n-grams

Tommy, I'm sure that I don't fully understand your use case and your data. Some thoughts: 1) I assume that fuzzy term search (edit distance <= 2) isn't meeting your needs or else you wouldn't have gone the ngram route. If fuzzy term search + phrase/proximity search would meet your needs, se

Partial word match using n-grams

One of our main use-cases for search is to find objects based on partial name matches. I've implemented this using n-grams and it works pretty well. However we're currently using trigrams and that causes an interesting problem when searching for things like "abc ab" since we first split on whi

But for this one document, where you get only the first sentence back from PH without "android" in it, does "android" in fact occur in that field for that document? Ie, it could be that document was returned because another field (e.g. title) matched, but the body field you are highlighting on did
