Preserving original HTML file offsets for highlighting

Hi all, I'm new to Lucene and have a question about indexing/highlighting of HTML files with Lucene. What I need to do is highlight the hits (terms) in the original HTML file (or get the positions of the terms/tokens in the original file). This problem has already been described by Fred Toth

Re: Are there any tokenizers that ignore HTML tags but keep the offsets so they can be used for highlighting in the original document?

Hi Ahmet, I am using Lucene.NET with C# so I can't test this quickly. Will HTMLStripCharFilter maintain the character offsets or does it just extract the plain text? Hans You can use org.apache.solr.analysis.HTMLStripCharFilter. It is possible to add one or more

Are there any tokenizers that ignore HTML tags but keep the offsets so they can be used for highlighting in the original document?

to write a tokenizer that strips out the HTML tags but maintains the original offsets within the HTML document so they can be used for highlighting the original HTML document, not just the text representation. Does anybody know any tokenizers that can do this? It seems it's something other people
