I check Crawling logs,

Crawling Information

Session ID 20240503083101

Crawler end time 2024-05-03T08:31:47.407+0000
Crawler exec time 40802

and found Index size (Web/File system) is zero.
I deploy FESS using docker-compose,say command
"
docker-compose --env-file .env.elasticsearch -f compose.yaml -f compose-elasticsearch8.yaml up -d
"

My pdf files are written in Chinese.

Would you please help me out of such situation?

Included Paths For Crawling ..(pdf|doc|docx|xls|xlsx|ppt|pptx|txt)$

This setting excludes directories from the crawling process: file:/var/lib/fess/.

Thank you Shinsuke Sensei.I am a greenhorn to Fess, and would you please tell me the correct way to crawle what I want?

[CANdy]

Included Paths For Crawling

the parameter is

[shinsuke]

A directory is a target path that the crawler scans. Therefore, you should add the directory to the Included Paths For Crawling . However, the file protocol cannot determine whether a path is a directory. Thus, you should use the SMB protocol and add .*/ to the settings.

Many thanks to Shinsuke Sensei.
I tried several settings to search my pdf files but failed. My settings like below.Would you please tell me the right way to search my pdf files?

Shinsuke Sensei,I am really appreciated to your kindness.
I set parameters following your instruction,however, I still got no search results from net shared file containning pdf files.
I am confused about my settings and have no idea how to solve it.

[shinsuke]

Could you please check the fess-crawler.log? It should contain the logged paths that were crawled.

[shinsuke]

This covers the same topic, but in Japanese. It wants to crawl XLS files.

[CANdy]

Shinsuke Sensei，I am very glad to tell you I finally get the right search result.
However,I have no idea about the reason.
The most important thing is to thank you for you patient and kindness on helping me out.
If Sensei explain the reason why it works or add them to document, I would more appreciated.

My setting belows:

the difference is the paths: smb://ip/, I ignore the username and password.

the Jobs,

I delete the old Job and create new one.

Since I do not have enough information to reproduce the issue, I am not certain of the cause. If you encounter an unknown problem, it is better to check the log messages at the debug level. To change the log level, you can set .logLevel("debug") in the crawler job.
