full text search - What is the maximum possible value range of MATCH ('...' IN NATURAL LANGUAGE MODE) in MySQL? -


mysql provides fulltext indexes, can retrieved match (col1,col2,...) against (expr [search_modifier]) construct. there several full-text search variants, 1 of them (and default one) natural language full-text search.

so maximal possible value of match ('...' in natural language mode)?

example:

this query

select     courses.id,     courses.title,     match (coursedata.title) against ('basketball') relevance     courses join     coursedata on coursedata.id = courses.coursedata_id     match (coursedata.title) against ('basketball') > 0

returns result table column relevance, we're storing relevance value of coursedata.title rows 'basketball'. or relevance value of 'basketball' coursedata.title rows? anyway, we're storing there output of match(...) function. in case i'm geting values 0 3.695953130722046.

there not small limit possibilities of query output. instead of reaching huge limit, freeze down mysql / network.

(c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
