Qsirch provides powerful search capabilities by analyzing metadata and using AI-powered search technologies. You can search for images (and people or objects within images), documents, emails, videos, music, and Microsoft Office files.

Basic image search

Qsirch can retrieve images based on embedded file details, including file name, type, modification date, and size.

• Using metadata to find an image: You can refine your image search by using the following attributes:
  File name, file type, general file information, date and time, camera and lens information, photography settings, and F-number.
• Using map search: You can search for images and videos based on their geographical metadata if your device has recorded the location data of your photos.

Advanced AI image search

Qsirch utilizes advanced AI-powered search to help you find images based on content, meaning, and visual elements.

• Using keyword search: Keyword search can detect and retrieve images that contain specific keywords, even if they are not present in the file name. Additionally, it allows users to refine search results based on attributes such as keywords, colors, and object detection to ensure more accurate and relevant results.
• Using semantic search: Semantic search analyzes word relationships, user behavior, and search context to deliver more precise and relevant results.

Object detection and categorization

Qsirch automatically detects objects within images and categorizes them into groups such as people, sports, animals, food, nature, and transportation, allowing users to find images using keywords related to these categories.

• Using color search: Color search allows users to filter images based on specific colors. This feature is particularly useful for finding images with a certain aesthetic or theme.
• Using AI OCR (Optical Character Recognition): AI OCR can detect and extract text from scanned documents, images, and image-based PDFs. It recognizes individual characters, forms words and sentences, transforming scanned content into an editable and searchable text document.

People search

Qsirch allows you to search for images based on a person's face.

1. Select AI Image Search on the Qsirch home page.
2. Upload a picture containing the person you want to search for from your computer browser or NAS folder.
3. After uploading the image, select People Image Search.
   The AI engine will detect the person's face and display a box around it.
4. Click on the person's face to search for other images that also include this person.
   The search results will display all relevant images stored on your NAS.

Object search

In addition to people search, AI Image Search allows you to find similar objects within images.

2. Select Crop to Search, then crop the image to focus on the specific item.
3. Qsirch will analyze the cropped selection and display images containing similar objects from your NAS.
