Result accuracy

Anonymous

#85995

My client is using the search plugin for chemical products, the results are not accurate, as an example searching for N-(4′-Chlorobiphenyl-2-yl)-2-oxo-1,2-dihydropyridine-3-carboxamide returns 285 results, it seems the search engine is only matching the word hydro.

That string of text is not at the top of the search results.

It will only come to the top and return as one results if searching for the word Chlorobipheny

Are there settings I am missing? Is it perhaps the use of hyphens and no white spaces that are causing this?

I think this may be the way that WordPress treats symbols and thus it may be breaking the terms down into smaller words.

The only alternative is to try installing relevanssi and seeing if enabling that (in the S&F Form Advanced settings) makes a difference (in some installations, it is also necessary to tell relevanssi to index and search in excerpts).

Are these chemicals also tags, as you can ask Relevanssi to search categories, tags etc.

Hi Trevor
I have relevanssi installed and have been using it. It does not seem to make a difference, it is set to search in excerpts.

Searching for the title does not seems to work.

As another example searching for p-Methoxycarbonylaminobenzenesulfonamide

does not find that result, searching for Methoxycarbonylaminobenzenesulfonamide returns no results

this is the actual page http://www.eppltd.com/products/p-methoxycarbonylaminobenzenesulfonamide

Are these long words mainly in the titles, and if so, did you add a weight to titles (like 1000 or even higher)?

Hi Trevor
I have adjusted the weight for titles to 2000 then tried 3000, neither made a difference

I am not sure what is going on then. It might be an idea to post on the wordpress relevanssi support page. What happens if you do not use relevanssi?

the reindexing for relevanssi wasn’t working properly but has since saved, it’s a lot better now, searching for N-(4′-Chlorobiphenyl-2-yl)-2-oxo-1,2-dihydropyridine-3-carboxamide does return in the results, just that it’s 4th in the list when the expectation would be that it’s returned first?

As I said, I am not sure. It may be the sheer length of the ‘words’ that is the issue.

This could be all manner of things. Those symbols might well be reserved. Given the number of symbols being used, this may happen on other symbols too.
