问题 I have problem on db search with like and elastic search in Turkish upper and lower case. For example I have posts table which contains post titled 'DENEME YAZI' . If I run this query: select * from posts where title like '%deneme%'; or: select * from posts where title like '%YAZI%'; I get correct result but if I run: select * from posts where title like '%yazı%'; it doesn't return any record. My database encoding is tr_TR.UTF-8 . How can I get correct results without entering exact word? 回答1

问题 I am trying to optimize the search for a string in a large text file (300-600mb). Using my current method, it is taking too long. Currently I have been using IndexOf to search for the string, but the time it takes is way too long (20s) to build an index for each line with the string. How can I optimize searching speed? I've tried Contains() but that is slow as well. Any suggestions? I was thinking regex match but I don't see that having a significant speed boost. Maybe my search logic is

问题 I have a ListBox with a certain amount of items in it. For each item in the ListBox a corresponding text file exists in the file directory. I need to search each text file (based on what's in the ListBox) for a persons name. Each text file may contain the name or it may not. I would then like a return which text file contains the name.

问题 This is just a speculative idea for a client who has a lot of PDF files. Algolia say in their FAQs that to search PDF files you first need to extract the text from the file. How would you go about this? The way I envisage the a system working would be: Client uploads PDF via CMS CMS calls some service / program to extract the text Algolia indexes the extracted and it's somehow linked to the original PDF It would need to be an automated system as the client shouldn't have to tell it to index.
