full text search - MySQL fulltext: have a result weigh more -

-

I have a database of cities and states (approximately 43,000) and I do a full text search on it: Select (against the City, State_Short, State) match (city, state_short, state) (select Q: in Boolean mode), where the number from Pincode (where city, state_short, state) is against (: Q in Boolean mode) Based on the city, state order score 6 by the score order

When I make a meaningful string to : q , work it But I say that I search for Houston Texas , I should be the first of the result, but instead it is the third:

  • Answer Houston, Texas
  • South Houston, Texas
  • Houston, Texas

    How do I Houston, Texas can weigh more than 2? This should be clearly similar to other such cities.

    Edit

    Does this work, any thoughts on this? 

      from SELECT * (select city, state, matches (city, state_short, state)) (as in BOOLEAN MODE q) (Score: BOOLEAN in MODE) as zipcode by score (City, State_Short, State) Group according to the limit of DESC by city, state order 6) Order by DTH, Length (city) Post-text "itemprop =" text "> 
     Your new query may work, but it is completely circumstantial, instead of  ORDER BY LENGTH (city)  Something like this would be  ORDER BY ABS (LENGTH (: q) - (LENGTH (city) + LENGTH (state))  This is not correct, but it should be better because the length of the input is equal and any higher point maybe what you are searching for. The last query will look something like this:  
      Choose against city, state, match (city, state_short, state) (where in the boolean mode) scores from zipcode match (city, state_short , State) against the (: Q in Boolean mode) Group, by the City Order, DESC, ABS (LANGTH (Q) - (LENS (City) + LENS (STATE)) DISC limit 6   
     I remove the sub code in the new main code in the new  ORDER BY  section transfer The result will be the same (or possibly more accurate) results.  
     Levenshatan distance is probably a more accurate solution for this, but there is no basic implementation of it in MySQL, a MySQL implementation of Levenshtein distance function There is more information about.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

ios - Replace text in UITextView run slowly -

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from. NSString will be used instead of NSMutableString . - (UITableViewCell *) TableView: (UITableView *) Table View CellForOutPath: (NSIndex...
