Example Usage

There are two steps to use this application:

1. First, you need to create the index and generate embeddings for the PDF file. Here I'm using a PDF file generated from this page Parable of a Monetary Economy

Before running this, you need to set up your OpenAI API key. You can get it from OpenAI.

export OPENAI_API_KEY=<your-openai-api-key>

The run the following command to start the training process:

dr-doc-search --train -i ~/Downloads/parable-of-a-monetary-economy-heteconomist.pdf

The training process generates some temporary files in the OutputDir/dr-doc-search/<pdf-name> folder under your home directory. Here is what it looks like:

 ~/OutputDir/dr-doc-search/parable-of-a-monetary-economy-heteconomist
$ tree
.
├── images
│ ├── output-1.png
│ ├── output-10.png
│ ├── output-11.png
...
│ └── output-9.png
├── index
│ ├── docsearch.index
│ └── index.pkl
├── parable-of-a-monetary-economy-heteconomist.pdf
└── scanned
    ├── output-1.txt
    ...
    └── output-9.txt

Note: It is possible to change the base of the output directory by providing the --app-dir argument.

2. Now that we have the index, we can use it to start asking questions.

dr-doc-search -i ~/Downloads/parable-of-a-monetary-economy-heteconomist.pdf --input-question "How did the attempt to reduce the debut resulted in decrease in employment?"

Or You can open up a web interface (on port :5006) to ask questions:

dr-doc-search --web-app -i ~/Downloads/parable-of-a-monetary-economy-heteconomist.pdf

There are more options for choose the start and end pages for the PDF file. See the help for more details:
