# Nextant > Navigate through your cloud using Solr **Nextant** performs fast and concise _Full-Text Search_ within: - your own files, - shared files, - federated cloud shares, - external storage, - server-side encrypted storage, - your bookmarks. ### Recognized file format: - plain text, - rtf, - pdf, - jpeg & tiff (will requiert Tesseract) - html, - openoffice, - microsoft office, ## Installation - [You first need to install a Solr servlet](https://github.com/nextcloud/nextant/wiki) - Download the .zip from the appstore, unzip and place this app in **nextcloud/apps/** (or clone the github and build the app yourself) - Enable the app in the app list, - Edit the settings in the administration page. - Extract the current files from your cloud using the **./occ nextant:index** command - Have a look to this [explanation on how Nextant works](https://github.com/nextcloud/nextant/wiki/Extracting,-Live-Update) - _(Optional)_ [Installing Tesseract](https://github.com/tesseract-ocr/tesseract/wiki) ([Optical Character Recognition](https://en.wikipedia.org/wiki/Optical_character_recognition) (OCR) Engine) will allow Nextant to extract text from image file and pdfs without a text layer. ## Building the app The app can be built by using the provided Makefile by running: make This requires the following things to be present: * make * which * tar: for building the archive * curl: used if phpunit and composer are not installed to fetch them from the web * npm: for building and testing everything JS, only required if a package.json is placed inside the **js/** folder The make command will install or update Composer dependencies if a composer.json is present and also **npm run build** if a package.json is present in the **js/** folder. The npm **build** script should use local paths for build systems and package managers, so people that simply want to build the app won't need to install npm libraries globally, e.g.: **package.json**: ```json "scripts": { "test": "node node_modules/gulp-cli/bin/gulp.js karma", "prebuild": "npm install && node_modules/bower/bin/bower install && node_modules/bower/bin/bower update", "build": "node node_modules/gulp-cli/bin/gulp.js" } ```
