Google Search

My wife needs a Google search engine on her website onthejob.education. This site consists of 100's of static webpages with relevant metadata on each page. She needs to let anyone coming to her site to search 1)metadata and 2)any content. The simplest and most frequent search would be to search for a job eg. architect or eg. data analyst or eg. vetinarian. As the site conent changes as often a daily the search data needs to be refreshed frequently. The site already has good visibility when searching in abrowser. What she needs is code to include a search box on 1 or more pages so visitors can search content. Hope this makes sense. Rob
