For specific thailand information, the thai-language search engines are best,
...if you can read thai; this effectively limits thai-databases/searches to thai's-only. Meta-search engines in thai-language
are currently not available. The www-single-engines and the 'multi-engine' meta-engines will 'blanket' thailand resulting
in a mixed return: useful + marketing. The best all-around sources utilizes
the www meta-engines with human-edited datafiles generated by websites with either an interest in thailand or asia, these
are usually euro-sites or asean-sites.
