>> Wouldn't it be easier to simply add "#" and "$" to the default lists of $phpdig_words_chars in config.php?
Hi. TMTOWTDI, but # and $ are not word characters.
>> For the rest of the special characters that are allowed in words (but not at the beginning) may I suggest an additional config parameter?
Maybe, but then there may be issues with what to escape and where... read on.
>> There is a little inconsistency with the backslash as could be expected from the fact that the two regexps (in search_function and in phpdig_functions) are not identical.
In search_function.php the backslash allows escaping '_% from user input to make literal characters. In phpdig_functions the backslash escapes ' to prevent a parse error.
>> I haven't completely figured out why, but if a page contains "word1\word2", the separate words are indexed, but...
The '._~@#$:&%/;,=- characters are allowed in search results, no backslash.
>> ...what CONTENT_TEXT means...
Basically CONTENT_TEXT set to one stores text content from crawled pages in the text_content directory. With CONTENT_TEXT set to zero then first_words from the spider table is used.
