The site has a job table that incorporates the following fields, (job_company, job_title, job_description, job_location) all the fields are Var except for description that is a text field.

This seems to work fine however I would like to improve the search results by adding in the

问题 I have a fulltext search table. It generally works well. But, in some cases it failed. For example; when I search for ' "red*" NEAR "color*" ' it works properly. However, if I search for '"the*" NEAR "red*"' it fails. It didn't work for any terms which starts with the -- working case SELECT * FROM MyTable WHERE CONTAINS(MyColumn, ' "red*" NEAR "color*" ') -- failed case SELECT * FROM MyTable WHERE CONTAINS(MyColumn, ' "the*" NEAR "red*" ') Does anyone know why? 回答1: What you are experiencing

问题 I've setup a fulltext index on my customer table to be able to quickly search for customers via their info.

问题 My code is similar to a file search engine, it takes in a keyword you are looking for, does a full text search of all the files in the users google drive and returns the files name, url source, and folder by displaying it in a spreadsheet.

问题 I have the following code that allows me to search through the data on a table by using the option buttons I created that match the table headings. I can set the search criteria to be exact matches or partial. However, what I would like is to be able to search through different columns in the table without always having to go into the VBA code to toggle this option on and off. i.e some columns I would like an exact match, others I would like partial. Any help on where I can amend the code

问题 In my Job listings site, I need to show jobs which have similar titles to the one which is being viewed. I am trying the following query, but its not working: SELECT *, MATCH(title) AGAINST "Sales Coordinator" as relevance FROM jobs WHERE MATCH(title) AGAINST "Sales Coordinator" ORDER BY relevance DESC LIMIT 100 Also, can this be optimized, so as to give better results and maybe faster too? 回答1: You really need to clarify what is not working (i.e. what is it not finding) and how fast the

问题 i have another question! I have an index with SPH_MATCH_ALL SPH_RANK_SPH04 and when i search for the word "ipad" the word "dissIPADor" is comming before the word IPAD alone, how can i make 'ipad' by itself, more relevant than "dissIPADor" ? 回答1: check that you are using version 2.0.2 or above of sphinx.

问题 I need to search a text in a SVN repository, inside all revisions. I am trying this software, which indexes all repositories and then you can search: http://www.supose.org/projects/supose/wiki #create the index ./bin/supose sc -U "svn://..." --username ... -p ... --fromrev 0 --create #search ./bin/supose se -Q "+contents:class" if i understood correctly, this should search across all files for the text "class". this should return a lot of matches, as there a lot of java files. however, it

问题 What I want to know what is difference between fulltext searching (searching data in files) and standard database searching (LIKE, IN ect). What I notice here is that in files you don't have data types, but in database you can define data types for particular data. I am interested in what kind of search is faster and what are advantages and disadvantages of both. Thanks. 回答1: There's a few advantages to full text searching. Indexing: Something like: WHERE Foo LIKE '%Bar'; Cannot take
