The Lycos spider T-Rex will index only the pages you provide. This is part of that inconsistency we mentioned. We don't expect this to become common place, but you should feel lucky if T-Rex does take a full walk through your site. It also gives a tad higher ranking for the number of sites linking to you. Lycos indexes meta tags, but they are just more text on the page to Lycos.
Searches are case IN sensitive.
It will use image ALT tags. They have not responded to several emails. However, one important email concerning my site was replied to indepth.
