I am trying to search the DOI field from the documents indexed using Lucene. The value for a DOI looks something like this "10.1186/1756-3305-7-73". Pardon me, in case the question is stupid, but this is the first time I am dipping my hands into Lucene.
The error is:
[2019-02-05 17:37:18,233] ERROR (ExceptionHandler.java:36) - field "doi" was indexed without position data; cannot run PhraseQuery (phrase=doi:"10.1186 s12937 015 0065 5") java.lang.IllegalStateException: field "doi" was indexed without position data; cannot run PhraseQuery (phrase=doi:"10.1186 s12937 015 0065 5")
Details of the question:
- Lucene version - 7
- Query expression - doi:"10.1186/1756-3305-7-73"
- Parsed query - doi:"10.1186 1756 3305 7 73" (notice that it removes forward slash and the hyphens)
- Analysers tried - English analyser, Standard analyser, Simple analyser
- Software used to navigate Lucene index - Luke v7.6.0
And no, I am not mistaken. The value for the field "DOI" is already indexed using Lucene.
Here is the complete log of the error:

I do have an intuition that the error here is related to parsing the query expression. I do notice that the - and / are parsed out of my original query, but I have no idea how to fix this. Any direction in the matter will be really appreciated.
