Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Incorporating the temporal property of words into query expansion methods based on relevance feedback has been shown to have a significant positive effect on microblog search.In contrast to such word-based query expansion methods,  propose a concept-based query expansion method based on a temporal relevance model that uses the temporal variation of concepts (e.g., terms and phrases) on microblogs. Our model naturally extends an extremely effective existing concept-based relevance model by tracking the concept frequency over time.Moreover, the proposed model produces important concepts that are frequently used within a particular time periodassociated with a given topic, which better discriminate beten relevant and non-relevant microblog documents than words.Our experiments using a corpus of microblog data (Tets2011 corpus) show that the proposed concept-based query expansion method improves search performance significantly, especially for highly relevant documents.
