[Taxacom] Species pages (index)

[Nicola Nicolson]

Hi,

Maybe you could try term boosting in Lucene to address this - at search time separate the search term into genus and species and give the genus part a higher priority. See :

http://lucene.apache.org/java/2_3_2/queryparsersyntax.html#Boosting%20a%20Term

cheers,
Nicky

Hi Ken,

I am just using the default Lucene settings for string searching at
the moment. I already had it pointed out that Wikipedia pages
(particularly for mammals) have embedded navigation templates at the
bottom that skews results.

Really this is an argument for getting pages marked up with just a
tiny bit of semantically rich information so we can link them rather
than try and guess it from the text context.

Thanks for your thoughts,

Roger
