I am trying to index PDF file in solr but looks like while converting text to UTF-8 characters are getting changed.
For example Below highlighted text:
Converted to:
Search applies on later keyword not original word. As far as I know this is happening while converting PDF text to UTF-8 before indexing.
For reference below is code for indexing:
String solrUrlString = "http://localhost:8983/solr/example";
SolrClient solr = new HttpSolrClient(solrUrlString);
ContentStreamUpdateRequest up = new ContentStreamUpdateRequest("/update/extract");
up.addFile(new File(filepage.getabsPath()), "application/pdf");
up.setParam("literal.id", filepage.getId());
up.setParam("uprefix", "attr_");
up.setParam("fmap.content", "attr_content");
up.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, true);
solr.request(up);
The language of the text content i suppose that you are trying to index is Gujarati , one of the Indian dialects. Solr do provide language analysis for a variety of languages , but I'm afraid in terms of Indian languages , it restricts itself to only Hindi . For Hindi, it provides following Analyzer classes classes: solr.IndicNormalizationFilterFactory, solr.HindiNormalizationFilterFactory, solr.HindiStemFilterFactory. I cannot see a one for Gujarati in the documentation. You can have a look at language analysis section of Solr here https://cwiki.apache.org/confluence/display/solr/Language+Analysis . So while Gujarati being the language in the question , i suppose analysis would be quite ambiguous, vague and incompatible . Let me know if you find anything better . Hope this helps :) .
