There are several issues that can arise when indexing research in the Arabic language.

Arabic script is written right-to-left, which can make it difficult for search engines to properly index and search for content. There are many different dialects of Arabic, and some search engines may not be able to accurately index and search for content in all of these dialects. Additionally, there may be a lack of standardization in the way that Arabic language research is written, which can also make it difficult for search engines to properly index and search for content.

Arabic script is written right-to-left, which can make it difficult to format references in the same way as references written in left-to-right scripts. Arabic referencing styles are different than those used in other languages, such as the use of Arabic numerals, the use of Arabic letters to indicate the volume of a journal and the use of Arabic letters to indicate the issue number of a journal. Additionally, there may be a lack of standardization in the way that Arabic references are written, which can make it difficult for readers to find and access the original sources cited in an article.

Another issue that can arise is the use of different transliteration systems, which can make it difficult to find the original sources when searching for them in English or other languages. Additionally, there may be a lack of availability of resources and tools to help authors with writing references in Arabic.
