How to Upload A File to Solr In Windows?

To upload a file to Solr in Windows, you can use the Solr cell functionality which supports uploading various types of files such as PDFs, Word documents, HTML files, and more. You will need to use a command-line tool called Post tool to POST files to Solr.

First, navigate to the folder where your Solr installation is located. Then, navigate to the exampledocs directory which contains example files for Solr. Copy the file you want to upload into this directory.

Next, open a command prompt window and navigate to the bin directory within your Solr installation folder. Run the following command to upload the file:

post -c <collection_name> <file_name>

Replace <collection_name> with the name of the Solr collection you want to upload the file to and <file_name> with the name of the file you want to upload.

After running the command, the file will be uploaded to the specified Solr collection. You can then query the collection to make sure the file has been successfully uploaded.
