php - SQL search query like stackoverflow -

-

In the user input field, such as

, I want to see existing articles to see if what's the same Are there. For example 

  SQL search queries such as stackoverflow   
 for example I Want to find the most relevant articles related to.  
 I know that something like this is:  
  'word' like WHERE article_title   
 But how do I get more than one keyword Manage   
 
 
 Use an integer index, which will be something like this:  
  SELECT ... to ... against WHERE MATCH (field name) ('keyword keyword keyword'); Hack the query to select   
 or  
  to ... from ... where (the field name '% keyword%' or ' % Keyword% 'etc ...)   
 Two, the full text version will be faster, because it can use an index like'  like ...% < / Code> version will be very expensive, because that type of wildcard search can not use indexes at all, the downside is that fulltext indexes only on MyISAM tables Plbd, and possibly Inodibi will not be available for the tables.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
